I vote get training. fwiw
Even online coaching. If you do the lifts correctly the only issue should be possibly squat depth. Which will come with weight loss.
Also you don't know what you're supposed to weigh yet. You may very well end up at 5'11" being a good 240 fully formed and that might be perfectly fine. Muscle doesn't take the same space as fat, you'll shift composition and possibly find your goal weight isn't usually as low as you think it is. When I started I thought my goal weight should be 135. Ha! Nope. Not unless I want to look like the Cryptkeeper.
Be sure you are on your heels. I noticed body weight squats tend to enable being on one's toes. That was my experience anyway, ymmv.
