Any problem with a bike is annoying, especially if it causes you to hike back instead of ride. I think the real trick is knowing enough to solve most of your own problems. Not every shop is a good shop, and even good shops will take a while to turn around your bike. IMO Skills a new rider should prioritize are:
I am convinced that some days my bike just does not like me. Sometimes it pulls the tires out from under me, it goes left when I want to go right, tires go flat, etc. I try to be nice to it. It just gets a desire to induce pain when I least expect it.

Second everyone on the creaks! I’ve been fighting a creak in my drivetrain somewhere for 2 years. Same with my seat. I can do full on fork rebuilds but cannot conquer these damn creaks! Have basically given up.
Also oils and greases too. For oils, when do I really need to use the manufacturers brand oil? Or what are options for using more commonly available oils instead of the crazy over priced bike brand oil. For grease; what grease for different areas? Or is there one type that can handle most areas? I basically use 2 types in different areas based on my judgement (light and heavy). No clue if I am using them correctly. Might be good to hit on areas you can use either oil or grease (like hubs) and what is the difference.
I was having trouble getting my front brake disc centered enough in the caliper to not drag (Guide RE). That was annoying. In the process of attempting to remedy that I overtightened one of the bolts and stripped the threaded hole in my fork. That was more annoying.
I did this when I was first installing my brakes. The thing that really chafes is I was using a torque wrench and was only at 4-6nM. Eventually that bolt fell out but was easy to replace at Home Depot and I got some spares in case it happens again.
