But, also what's happening is thickening of thighs, midsection, and biscuits (butt)....not good for me.
Is this FAT or is it muscle gain? Or is it part both?
See the problem with getting significantly stronger is that it's easier to do while putting on muscle and some fat at the same time which it looks like you were doing.
Keeping an isocaloric diet and doing heavy strength work will make you stronger but it will be significantly slower. On pure CF you might not see that much strength gains, heh.
