Brief summary: This phase II trial studies the effects of venetoclax and rituximab in comparison to ibrutinib and rituximab in treating patients with previously untreated Waldenstrom's macroglobulinemia/lymphoplasmacytic lymphoma. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving venetoclax and rituximab may work better in treating patients with previously untreated Waldenstrom's macroglobulinemia than ibrutinib and rituximab alone.

Detailed description: PRIMARY OBJECTIVE:

I. To compare the rate of very good partial response or better (VGPR or better) in previously untreated participants with Waldenström's macroglobulinemia (WM)/lymphoplasmacytic lymphoma (LPL) who are treated upfront with ibrutinib plus rituximab (IR) versus (vs.) venetoclax plus rituximab (VR) regimen.

SECONDARY OBJECTIVES:

I. To compare overall response rates (ORR) in WM participants treated upfront with IR vs. those treated with VR.

II. To compare progression-free survival (PFS), time to next treatment, duration of response in WM participants treated upfront with IR vs. those treated with VR.

III. To compare the rate of complete response (CR) in WM participants treated upfront with IR vs. those treated with VR.

IV. To evaluate the safety of the IR regimen as compared to VR regimen in participants with WM.

V. To evaluate the time to VGPR in WM participants treated upfront with IR and those treated with VR.

VI. To evaluate the ORR in participants who progress on treatment with IR and VR and are crossed over to the other respective arm.

VII. To compare overall survival (OS) in WM participants treated upfront with IR vs. those treated with VR.

BANKING OBJECTIVE:

I. To bank specimens for future correlative studies.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive ibrutinib orally (PO) once daily (QD) on days 1-28 of cycles 1-24 and rituximab intravenously (IV) on days 1, 8, 15, and 22 of cycles 2 and 5. Cycles repeat every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity. Patients with progressive disease during Arm I may receive rituximab and venetoclax as in Arm II for up to an additional 24 cycles. Patients undergo computed tomography (CT) or positron emission tomography (PET)/CT and bone marrow biopsy and aspiration as well as blood sample collection throughout the trial.

ARM II: Patients receive venetoclax PO QD on days 1-28 of each cycle and rituximab IV on days 1, 8, 15, and 22 of cycles 2 and 5. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity. Patients with progressive disease during Arm II may receive ibrutinib and rituximab as in Arm I for up to an additional 24 cycles. Patients undergo CT or PET/CT and bone marrow biopsy and aspiration as well as blood sample collection throughout the trial.

After completion of study treatment, patients removed from protocol prior to progression are followed every 3 months until progression, death or 5 years after initial registration, whichever occurs first. Patients followed after progression of disease are followed every 6 months until death or 5 years after initial registration.

* Testing to establish baseline disease status must be performed within 28 days prior to registration
* Participants must have at least one of the criteria to require therapy for WM including anemia, thrombocytopenia, neuropathy related to WM, symptomatic hyperviscosity or serum viscosity levels greater than 4.0 centipoises, WM associated glomerulonephritis or renal disease, bulky disease, or constitutional symptoms. Constitutional symptoms can be described as unintentional weight loss \>= 10% within the previous 6 months prior to screening; Fevers higher than 100.5 degrees Fahrenheit (F) or 38.0 degrees Celsius (C) for 2 or more weeks prior to screening without evidence of infection; Night sweats for more than 1 month prior to screening without evidence of infection; Clinically relevant fatigue which is not relieved by rest due to WM
* Participants who require ongoing use or received a moderate or strong CYP3A inducer, moderate or strong CYP3A inhibitor, P-gp inhibitor within 7 days prior to the first dose of study drug will be excluded from the study. If such participants can be safely switched to an alternative agent, then the participants will be eligible to enroll

* Participants must be \>= 18 years of age
* Participants must have history and physical exam within 28 days prior to registration
* Participants must have Zubrod performance status =\< 2
* Participants must have evidence of adequate renal function, as defined by creatinine clearance (CrCl) \>= 30 mL/min. Values must be obtained within 14 days prior to registration

* Participants must be able to take and swallow oral medication (capsules) whole. Participants may not have any known impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of the study drug (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection)
