What Teeth Amount for new 9 Speed Cassette

So looking for a new Cassette... Currently have the Felt F95 with the Sunrace 9 Speed Cassette... Looking to swap this to a Shimano Casette, probably the HG50. My bike uses Shimano Sora gearing.
Currently have 11-25T Cassette, wondering what would be best though as can see lots of different options available. I do standard ride, quite a lot of climbing as quite hilly where I live... Don't think I get much use out of the fastest gear I have available...
Is there one which will give me an easier time climbing, but also able to keep up a good average speed? Usually average around 17mph?

I think you can get 12-28 as well? And, I'm not sure if the 30T requires a longer cage RD?
Random question, how many links is your chain? I used some calculator and it says I need a 53 link chain when I change. However, chains come in 2 sizes usually 114 and 116 lol...
