Some options that spring to mind for a more "serious" full-body isometric workout:

* Suitcase holds

* Pull-up holds

* Standing in a power rack with heavy barbell on back

* Bench press holds at the bottom (pressing just hard enough to keep weight off the chest)

* Overhead holds

Quite a few plank-variation-type options from the yoga world as well.

It’s more of a hybrid exercise but “pause squats”, in which you hold the weight at the bottom position before coming back up are a very good variation of a standard squat.
