Debris caught between caliper/pad, pad needs more brake anti-squeal compound on it, or the caliper pins need to be lubed.
Only real way to tell is remove the wheel and manually spin the rotor…. Spray off with high pressure air to blow away any debris. Squirt down with a good Brake cleaner and go for a ride. If the noise is still there then you’ll have to dismantle the pads to put anti squeal compound on backsides of the pads..
I’ve also seen it where the brake pad wear indicator becomes bent and can touch the rotor ever so slightly - so look for that and/or slight scoring on front OR back side of rotor.

Cobra Jet, you're always so helpful and clear, thank you.
I did notice the first time you mentioned the slide pins you said to lubricate them which is what needs to be done. The second time it seems to say to put anti squeal on the pins. You don't really want to do that. I'm positive you meant to lube the pins. I'm not trying to be critical, just don't want to see someone misunderstand.

Maybe somebody can answer this. I think the previous owner put on track pads. If they’re not up to temp, they randomly squeal so loud, even when braking at 5mph. The brake pads aren’t worn out. Still have a lot of meat on them.

Even if your brake pads seem alright at first glance, it's worth giving them a closer look. Sometimes, they can get a bit shiny or wear down unevenly, which might cause that annoying squeak. Try gently sanding the surface of the pads to rough them up a bit and see if there's any weird wear or damage. Plus, all that brake dust buildup could be making noise too. Giving everything a good clean, from the pads to the rotors and calipers, might just silence those squeaks.

Whoops - yep you caught a misspelling and a revision of that sentence there! The second or ending sentence of that line was supposed to read “pads” again, not pins….
Sorry for any confusion there (corrected my post).

Pretty much depends on what you use the car for.
For daily or occasional use there's no real reason to use anything other than stock. Track or overly aggressive driving might warrant an upgrade.
20k miles shouldn't be enough for stock pads to need replacement. They should easily go twice that or more. Have you pulled the wheels to check them yet? There have been several good suggestions to help you find the source of your noise. Until you investigate more it seems planning to replace the pads is premature.
