One fairly cheap bedroom addition I can't recommend enough is blackout curtains. Took me 25 years to discover that they're a thing, and the improvement in quality of sleep has been immense for me.
Personally I prefer to allow the sun to wake me (and I don’t nap).
With the curtains I have an extreme tendency to oversleep or wake unnaturally from something like an alarm in the middle of rem sleep and be all groggy. Prior to getting them I would just wake naturally between 7-7:30 in the summer and 6-6:30 in winter.
Sometimes I sleep on my couch in the office so that I can wake naturally that way.
