If we are talking about a painless entry into 3D printing, then Prusa would definitely be a good choice. Alternatively, you may want to consider buying an additional plate for your workbench. The kit comes with only a smooth plate - https://botland.com.pl/czesci-zapasowe-drukarki-3d/19935-plyta-ze-stali-sprezynowej-z-samoprzylepnym-arkuszem-pei-do-drukarek-prusa-mini-gladka-5904422350130.html, and a textured(https://botland.com.pl/czesci-zapasowe-drukarki-3d/19934-plyta-ze-stali-sprezynowej-pei-do-drukarek-prusa-mini-teksturowana-5904422350123.html) and satin(https://botland.com.pl/czesci-zapasowe-drukarki-3d/19936-mini-plyta-ze-stali-sprezynowej-pokryta-dwustronnie-pei-napylanym-proszkowo-satynowa-5904422351700.html) version is still available. The different plates make it easier to print and adhere different types of material, this is detailed in the form of an intuitive table on Prusa's website - https://help.prusa3d.com/pl/materials. Another thing worth considering is printing glue, it is useful for more problematic prints and more advanced materials. Isopropyl alcohol for cleaning the surface of the work table is also useful - https://botland.com.pl/smary-i-oczyszczacze/5707-kontakt-ipa-plus-alkohol-izopropylowy-1000ml-5901764329480.html. The last improvement is a filament sensor - https://botland.com.pl/czesci-zapasowe-drukarki-3d/20956-czujnik-filamentu-do-drukarki-3d-prusa-mini-5904422383077.html, it can come in handy for long prints when you are not sure if there is enough material on the spool, this sensor when it detects the lack of material will stop the printer.
Of all these things, for the beginning I would stock up on glue and isopropyl alcohol, possibly one additional plate.
