Any kind soul on DIY know what kind of valve this is? Dual flush? I ask because another one of my toilets has it and the bulb arm snapped off and I need to do some fixing.
(ignore the obscene iron buildup)

Looks like a standard riser. I've replaced many of those over the years. You can find them at any decent hardware store, including just replacing the float and arm if you want.Or you can replace the whole unit with a Fluidmaster kit. It's the tall piece on the left in this pic. Has a black float. You can adjust the height to match how much water you want in the tank. It usually costs a bit more but is a decent quality kit.

It's called a ballcock valve. One ball, one cock.

I've have the Korky QuietFILL Platinum Universal Toilet Fill Valve (Mfr # 528MP) that I installed on my ancient toilet years ago. Easy install and quiet fill. Under $20.

Warning: some of these newer replacements fill extremely fast, compared to the old ones, but they're a little sensitive if the water has a lot of rust/sediment coming though. They can jam up.

Better late than never but that's a Mansfield toilet with a ballcock fill valve. The ball type fills faster than a 400a fluid master...and that's the wrong toilet handle..the Mansfield handle is chunky plastic.
