In all cRPG games I've played at a certain point money becomes a matter of no concern as you are swimming in it.
I've seen a mod for BG2 where you "lose" a certain amount of money every day.
Bg3, no day cycle? Then make it per Long Rest - let us say ... hmmm ... 500gp or maybe 10% of monetary wealth per LR?

Another thing I'd like to see - fast travel only between one gate and another, i.e. the entire party has to be within a certain radius of the Rune to teleport. Combined with "click to point on map and have the party trudge there".
