In that regard, the 2nd edition of Pathfinder reached a more balanced middle ground between character creation options, "roleplayability" and swift combat mechanics, IMHO. I hope some studio would make a game using pf2e. Maybe it´s because I´m used to the almost infinite builds you can make and I like PF1e, but I understand that PF1e can be a little overwhelming at first.
5e is fine, but the strong point is not the complexity of the character creation options in comparison with other tabletop games like pathfinder, TDE, Starfinder, etc... or previous instalments of D&D.
If you want games with great character creation options and party-based you could try the games based on the Tabletop "The Dark Eye" like the Drakensang series or Realms of Arkania series.
You can even try old titles with rich character creation options like Temple of elemental evil, arcanum or Pool or radiance or even more modern games like NWN2 or Pillars of eternity 2. You can make an incredible amount of multiclass builds with the latter to complete your party, and all classes are very balanced ( The best defensive builds are multiclassing enchanter wizards, for example =D )
There are a lot of dungeon crawlers too that have very cool party creation mechanics (Demon rise series, battle chasers, Etrian odyssey, etc) or even tactical games like Fire Emblem or Tactics ogre titles.
