Although I prefer a point-buy system or standard array in 5e, especially for all-around game balance,
it is a bit too severe in 5e core.
Many characters end up with maximum 15 or 16. Even with a more flexible racial exceptions, as made official in Tasha's Cauldron of Everything, your Paladin Dwarf would have maximum 16 Charisma or your Dwarf Wizard maximum 16 Intelligence. And 16 is already much better than the official rules of point-buy and races a few weeks ago. :P
Games that allow both point-buy or rolls freely, like in Solasta, means that some players roll with 18s while others play a very moderate array of about 15, 14, 13, 12, 10, 8.
CONCLUSION / SUGGESTION : a standard point-buy for all players, which creates a more comparable playing field, BUT a bit more generous or epic than the 5e standard.
( something along the lines, more or less, of 16 15 14 13 12 11 before any racial bonuses. Which is 13 more buy-points than the 27 usual. )
