Definitely using the base-width filter a lot these days with very low width to dial in the exact frequency range. Since it’s a 1-pole filter it still lets in plenty of frequncy bands even with a low width, so dont be afraid to make it pretty narrow.
Also, ratios. Setting ratios in a similar range - like 1.00 + 2.00 + 0.75 instead of 0.5 + 4.0 + 16.0 helps the harmonics stay in a similar range. It’s kind of like the Range (16’ 8’ 4’ 2’ etc) on an analog synth
Subtle FM with modulation I find more effective than harsh FM + filtering. Some pads dont even really need the subtractive first filter if they’re pretty simple harmonics with subtle FM and everything else is dialed in nicely. I anyway prefer the gentler LP2 filter over the LP4 filter for pads so it’s good to start with the filter off and make something that sounds nice even with the filter all the way open
Also, starting with harmonics at 0, you can still make a lot of great sounds FMing sine waves in slight ways using different algorithms
Also making use of the filters in the effects, e.g. the HPF in the chorus, not making the width fully 100%, and using the base-width filters in the delay and reverb etc
