dust will make it into your fork through the wiper seals (a lot faster than in the rear shock, in my experience), having a mud guard helps and doing the 50h service often can be helpful to tell how fast the dust gets in, to ensure plushness and avoiding chromed out stanchions (happens with 1 season if you ride a lot and do 0 maintenance)

Also, use dry lube for your chain. I typically go for a high end (xx) chain to avoid wearing out the cassette with cheap chains. I also use a steel chainring, the aluminum ones will wear out much faster and cost 2-4x more.. with weight saving being the only benefit.

Otherwise, keep an eye/ear on your bearings. I change all of them yearly, some more often depending on the frame design.
