I'm not sure I agree with all your points. Especially the goblins. They are nowhere near as strong as the intellect devourers, for example. And their hp, except for some special named characters is around 8-12, which seems normal for levels 1-2.
As per 5e rules, the bulette does not need a running start. It can use a bonus action to make a standing leap of 30 ft (which translates to 9-10 m here) AND gets that knockback if the leap is more than 15 ft.
I agree about the minotaurs, though. Their charge works for even point blank, but the knockback requires a running start of 10 ft (3m here).
Not sure about the hook horrors.
Also, shove and knockbacks in general have been boosted. 5e uses 5ft (1.5-2 m here) knockbacks as the default, with exceptions like the minotaur, but the base here seems to be 5m or more.
Regarding goblins: only at the beginning do they go 8-12. Once you get across the bridge it appears 12 is the minimum, whereas many more have 24-30 HP. I wouldn't have much issue with this though, but had to point out the difference because it is still a pattern.
Regarding bulettes: I'm well aware the bulette doesn't need a running start. It's still 9m. Whereas the Larian version jumps a lot farther than that, possibly almost double the distance. And in 5e the knockdown only affects things in the Bulette's landing space, whereas the Larian version hits everything in a AOE around it.
