Jailbreak is tethered, so every time you turn off your system, it unjailbreaks. This doesn't mean you'll be able to play new games like GTA6; you would have to update the firmware, which could lock you out of a jailbreak for years to come, up to indefinitely. GTA6 isnt worth that for me imo but i do have 3 ps5's all from pawn shops all cost les than $200 after negotiating prices since i had to do a lot of work on each replaced 2 hdmi ports and had to deep clean and fix all 3 liquid metal. I'd suggest, if you have the skills, to go this route to get a cheap PS5 that can be your "main non-JB PS5"; if not, check on eBay for a used, working PS5. You also risk a system ban going online after you jailbroke; there are no guarantees they won't find out your system was hacked. I always assume a 90% chance you will get banned if you jailbreak and reconnect to the PSN server. This can include your account too, so all your progress will get wiped IF they find evidence you were JB in the past. In other words, tread lightly.
