IME most groups use a bonus level 1 feat houserule, or the Theros equivalent optional rule.Fighting Initiate is a curious feat. I wouldn't use it very often but used correctly it isn't too bad a feat.
Its undoubtedly better with UA fighting styles like Mariner but it does have some uses. taking Defense style with a heavy armor/full plate character is pretty good since its an all the time +1 AC and I could see Dual Wielder + Two Weapon Fighting Rogues or Thrown Weapon Variant Human Paladins (axe for the win) or Rogues as well.
On the whole though, sans multiclassing 5E is less optimizable than you might think.
Two ASI's almost always go into the primary stat and that keeps you busy till 12th level which is where a fair number of games end.
Now if you are using rolled stats and get good rolls feats can be better of course.
Not Tasha's feats here but I had a Barbarian with rather high physical stats and taking Resilient /Dexterity and Shield Mastery made him quite tanky even at low levels.
A high roll might free up an ASI otherwise used for Con or something else.
On the whole though outside of niche/RP builds and a few optimizations like War Caster or the like and of course the stuff I mentioned above, charterers are so feat starved that most feats simply aren't worth it.
The general game assumption that you'll max you main stat, the reality is you have 3 ASI for twenty levels, maybe 2 if you boost CON as many do to increase durability. That isn't much really.
Now this isn't a bleat for "more feats." or something, 5E is good as is but its just being realistic . You are probably going to take one feat, maybe two if variant human in most games so choose wisely.
But yeah 5e just isn’t that breakable.
