I have a 1:7 twist so the fast load.
For arguments sake lets say I want this to be as accurate as I can get (at this point I'm just making practice ammo that won't ruin my day) what tools/equipment should I look into?
First, get to a point where what you have is holding you back from getting more accurate. Then consider spending more money. That 1:7 means more resistance to the bullet going down the barrel, as the lands are vectoring its forward thrust into circular rotation more than a slower twist barrel. That resistance translates to more pressure for the same powder charge. Maybe 21gr to start with is looking a little better. IMHO, your twist will benefit you a lot more if you like hanging around with the heavier, which usually equates to longer, .224 bullets. They need higher RPM to stabilize. You will do worse having too little twist than too much, where accuracy is concerned. If you were just interested in throwing lightweight pills at high velocity, then yes, a slower twist would be more optimum.
I have a Savage Model 12 BTVS which only has a 1:12 twist. Shoots 55gr and down like a laser, but it begins to struggle at 60gr and will not shoot the Hornady 68 and Sierra 69 BTHP bullets very well at the velocities I prefer.
