Regarding 30fps vs 60fps, you absolutely do get used to it, and I say this as a vehement PC gamer with a 144hz monitor who normally doesn't bother with consoles since PCs do everything they can do but better (exclusives aside).
30fps was horrible at first, but after about 20-30mins, I surprisingly got used to it. I did try performance mode for 60fps, but it is noticably less visually impressive. I've also switched between 4k SDR and 1080p HDR (as my TV can't handle 4K HDR). If I play on 4K SDR, the sun is sometimes horribly blinding, so I do play on 1080p HDR at the moment. 4K does look very nice though.
