I did this before but if I had to choose between PS4 Pro or PS5, I'd stick with PS4. The more you look into it the more you get PS5 is a pack of scams (like XBSX).
> minimalist shit UI, you can't custom anything, not even your PSN ID like PS4 or Vita
> removable disc drive that doesn't work offline
> Remakes and Remaster spam

Almost a surprise they didn't throw a Kinect bullshit to go along with the rest. After almost 5 years the best that PS5 can offer you is Stellar Blade and Dualsense Dpads (which actually is a copy/paste from PSP)
