Water damaged iPhone 7 worth fixing?

Hey everyone, recently my iPhone 7 had gotten water damaged, although I think I may be able to save it. The display doesn't display but it still recognizes touch and the phone still turns on, the U10 chip is shot (recognizes touch ID and the reachability function but does not click), taptic engine is broken, I don't think the battery holds much charge anymore, and I've got the issue with the Qualcomm chip coming loose with "No Service ⚠" at the top. Would it be worth it to fix? My concerns are:

1. its not the display thats broken but the connector

2. ill have to learn how to microsolder to get my service back (and home button click but I couldn't really care less about it because I still have touch ID)

3. Ill spend money on parts but the problem ends up worse than I though it would be after fixing

also a few things to note: I have fixed multiple phones so I'm not really scared to open my phone (I already have opened it to see if there is anything else wrong). if I put my phone to charge it will turn on and you'll hear the charge indicator noise thingy. sometimes when I turn on my phone I open up to an app with a keyboard and I can type.

Thanks everyone!
