Also don't forget about boots. They can be hard to fit and find a good pair but the effort is worth it. You might not care immediately and skis are more exciting to buy, but your boots are how you use the skis and bad boots can make it hard to get better.
It seems like after a decent period of experimentation many skis currently are just good, especially in the intermediate range. I don't know much about beginner skis but depending on what you learn on the next step up from rental skis will feel like a significant improvement.
After that, there is a lot of feel and style that determines the skis you might use. I have probably 10-15 pairs because I hold on to my worn out, broken skis instead of throwing them away. I figured out what characteristics I like for where I ski and a couple common conditions. Some people like long, straight skis, some are happy with shorter noodles, part of that is style and part of that is where the skis are used. Some people care a lot about weight.
I personally use all-mountain skis which are, well, good in most conditions because I typically ski in the Midwest with trips out west. If you frequently hit powder and/or live near a mountain a pair of powder skis may suit you well either alone or as a compliment - don’t over think it too much.
I highly highly highly highly recommend taking lessons next time you get to a real mountain. They are well worth the money. I usually do a tune up lesson to start the season the first time I get out west.
I’m not sure what your budget is and your ski frequency is but if you ski a lot I’d spend the most money you feel comfortable spending and buy a great pair of boots. Rent skis for a while if you need to. Then get a pair of skis. Don’t skimp on boots. Don’t buy cheap boots. Get them fitted at a ski store by a professional. Boots make/break your ski life.
Tl;dr
Buy an expensive pair of boots, it matters. Pay for lessons. They matter. Arcteryx jackets? Not so much.

If you don't know/care, you should probably go to the local rental shop and buy a pair from them at the end of the season.
