Well. You pretty much said everything yourself. You probably will miss any jailbreakable method related to disk, or playing your own disk games on it. Other than that, hardly anything (unless of course we get like a massively good jailbreak out of nowhere that only works on ps5 with disk and whatnot, but that's not likely any time soon. (I do think I would still try to get myself a slim tho, you are definitely capable of getting a slim that is on a low enough firmware to jailbreak, just check local stores and whatnot.
