I think of three kind of mud guards that fit the description: musguard, quickfix, and fender bender. An other solution is the ass saver, but this is not what you are looking for.
Fenders don't fall into an "ok with racks" or "not ok with racks" category. Generally speaking, most traditional fender designs will work on bikes with racks attached. There may be certain combinations of fenders and racks that are problematic, but those are the exception. An example of a problem would be a bike whose rear rack is very close to the top of ...
Use fenders with good coverage! They will keep most of the dirty spray water off your bike. You'll be surprised how much less oiling your chain needs with proper fenders. Proper fenders means: a front fender with a mud flap that reaches within a few centimeters of the road a rear fender that starts some centimeters below the chain stays, so that water ...
While the aluminum frame itself will be relatively ok, the problem will be your bottom bracket (almost certainly made in part of steel) which was most probably sitting in a big puddle of water. Even if the water didn't cause the bearings to rust, a freezing/melting cycle can cause damage to the bearings themselves, force lubricants out, and otherwise mess-up ...
Technically rust is limited to iron. What is bad is the rust starts and continues. The water / oxidizing agent is not consumed. Aluminum will oxidize but it forms a protective coating. An aluminum frame will not "oxidize out". Some iron alloys such as stainless steel prevent rust. I don't know why you don't seem to see stainless in bicycles.
Most standards fenders will work with a rack. You do have bikes designed for both - you will have two bosses. You can double up and use the same boss for both but a separate is much preferred. If a bike will take a rack then it will (almost always) take fenders. But you can have a bike designed to take fenders but not a rack. People use fender mounts ...
Store your bike in a dry place if possible. This is probably the most important thing - even if you ride every day, your bike spends more time parked than it does on the road. Clean and oil the chain regularly. If it's squeaking or showing rust, you're not doing it often enough. If you have loose bearings anywhere on your bike (hubs, pedals, bottom bracket, ...
The best way is not to ride your bike on rainy days at all. According to your own account, this isn't possible. So: Wipe dry the frame, bottom bracket, hubs, chain, crankset, etc. If possible, use an air blower to keep them dry. Use water-proof parts, like some hubs with a rubber ring to prevent water from getting inside them. Also using waterproof grease ...
Is the frame pure aluminium? Aluminium does not rust. If the frame is an alloy you would need to check whether or not the other materials are susceptible to rust.
Did you try BetaBrand. They are costly but these are the only cloths that I've found that meet that criteria. THey have a whole line of "bike to work" clothes https://www.betabrand.com/collections/bike-to-work.html
I've just spent some time looking online and found quite a few results on Amazon, Ebay, (you could also try wiggle, which is kind of like an online surplus shop.) unfortunately without seeing a picture of exactly what you saw, I can only paint a vague picture of what you're talking about. But any of those websites would be a good starting point. And, just ...
If its better integration of rack & fender you seek, look into getting a rack with a centerline stud or nut that you can attach the outmost half of the fender to. See this pic for a rear fender+rack example.
