Additionally, I hope that when I teach kids to CAD with a lot of features (for example on frame tubing, first the profile extrusion, then any wheel holes, then top gusset holes, then gearbox holes, etc), that they realize that the way they model a part should reflect what depends on what and how it will actually be manufactured. Of course, I can definitely see how you might find putting a lot of stuff in a sketch faster.

Most of the parts that I do the massive sketch for are essentially 2d parts (even tubing is 2d in my mind in many cases). I don't see how this makes the model less adaptable in any significance, I actually find it to be more reflexive as it's much faster/easier to change dimensions. If you want gearbox holes 4.5" spaced on center, how is it different to do that in the same sketch as the bearing block cut versus another feature in terms of robustness? However, putting them in the same sketch lets you see everything at once and iterate dimensions faster.

At some point I'll go over our swerve corner plates, that's a part that really literally I would not have done if we didn't do it one sketch, it just would've been too much time spent jumping between features.

Thanks for the tip on face fillet, that's a good one.
