These worked decent for me.

I have SKS fenders for my MTB and Planet Bike ones for my commuter. They're both absolutely necessary here in Washington. Fenders are the first thing I recommend to people I work with who ask me about commuting. They go a long way to improve the quality of your ride. Congratulations on your first commute.

Back when I rode a 7.2 FX, I installed these: https://www.amazon.com/gp/product/B0041X5ZX4/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Fit fine, worked great.

These are what I use, and they've been great so far. Good protection, they don't weigh a whole lot, sturdy construction, not too expensive, etc.

My main gripe is that they, like the ones you've tried, will require quite a bit of fiddly adjusting at first until they're perfect. At least, mine did. And if you take a spill, you'll likely need to re-adjust them again.

Plus, they're not the simplest to install, so quick, hassle-free removal, if that's something you're after, isn't really going to happen. They can be taken off, but mine bolt on between the frame and the brakes, so it's a bit of an involved process. And the rear one bolts on on the plate where the kickstand would go, and that definitely requires removal of the rear wheel to access. So, my fenders just stay on all the time. It's not been a bad thing, though, as I simply don't worry about it.

Fenders: these or these

Rack: Axiom Transit

Lights: Front and tail. If you want a rack-mounted tail light: light and bracket.

Helmet: go to your LBS and try on a few. One-size-fits-all helmets are not as comfortable.

Other: I'd also recommend a puncture kit for when the inevitable happens. Tube, tire levers, CO2 inflator and cartridge.
