Well at least there is some context here to work with. It appears your main focus is BJJ and everything else is just an accessory to that.
So time for the bad news. You'r not going to get near the objectives you set out (bigger quads and definition).... The reason: you don't train enough. What you want to achieve are bodybuilding goals and require a good amount of frequency a week. There is a huge misnomer out there and I hinted to it when I joked about the general public thinking lifting weights is "easy". Just as you practice amd train in BJJ with a plan towards fighting in local contests or even as simple as working on new skills, it takes dedicated training towards that task. Bodybuilding is the same (it is literally in the name). Your goals are bodybuilding goals. Unfortunately it comes down to choosing what your current priorities are....If you want to get jooicy big boy quads that burst out the short shorts that these gen-z'ers be rockin.
... then you will have to prioritize hard gym work (min 4 times a week). It also requires planning. That includes training and diet because what you are attempting to do is "build" your body.
Again if your priority is not that and you want to stick with BJJ that is fine. Your decisions are not terminal amd can always be adjusted. I do still suggest learning about how to optimize your diet and weight training protocols because that will have benefits for your BJJ and overall health.
