One of the worst mistakes people make with squash (especially the winter squashes like acorn, buttercup, kambocha, hubbard, and so on) is oversweetening them. Yukko! Kambocha makes fantastic tempura, and acorn does too…and those are light, thinly sliced, crisp on the outside, and a little salty from the dipping sauce.
Another way I like making acorn squash is a little compromise for those who like a touch of sweet in their baked squash - just a little bit of brown sugar (or better yet, maple syrup!) a small pat of butter, then sprinkle the whole thing prettily with good paprika and either white or black sesame seeds. heck, a little sesame oil instead of the butter can work too.
Edit - I forgot that one year I made a vegetarian Thanksgiving dish that involved baked acorn squash filled with a saffron/pine nut/ basmati rice pilaf…mmm. I’ve also made some other nontraditional holiday-season things like inarizushi made the usual way (sweet little fried tofu pockets filled with sushi rice) but the rice was mixed with toasted, lightly spiced pumpkinseeds. Those went over like crazy too!
Hubbards, I think are best in hearty winter stews, not anything sweet.
And lastly, if you can stand pumpkin pie (even people who hate pumpkin pie wolf mine right down - no idea why, since i don’t do anything different than anyone else - I suspect i just have a good hand at making custard and balancing spices), try acorn (or even better, buttercup!) squash pie, using much less sugar than pumpkin, and barely anything besides roasted, scooped acorn squash as the fillinng.

A little dab of sugar and spice is fine, maybe a bit of egg and condensed milk for texture, and it’s just beautiful, as well as very healthy!
