It absolutely is IPA. The pro stuff is usually especially high-purity (99.8%+) but nothing all that special. The only special thing worth getting for tape heads, capstans, transports, and CD/DVD laser lenses is a lint-free swab with a more square head than a q-tip.
Dish soap is fine on vinyl records, but use distilled water. The "residue" is more likely to come from unfiltered tap water than soap. And let them air dry completely before re-sleeving them because they can and will grow moldy, especially if the records are put away wet with paper sleeves.
You don't need a fancy brush for cleaning the stylus, but a polyurethane gel pot is even easier to use (just dip the stylus tip in it), more thorough, and trivial to clean.
And a cartridge/stylus upgrade, which for this setup probably doesn't need to be anything more than an $80 Ortofon Red and could easily be less. AFAICT this Pioneer has a replaceable cartridge.
I think the cartridge on my turntable may have already been replaced, but I'm not sure. The previous owner said it was her ex's and that he'd serviced it when he owned it, and the current cartridge is a Grado, which I understand is a reputable brand? I've still obviously got a lot to learn about vinyl haha.

The only "fancy" vinyl accessories that've really provided a lot of value for me are a grounded anti-static brush: https://www.turntableneedles.com/grounded_carbon_fiber_lp_br...
