Didn't yet check if it has ability to manually set specific TX fee when doing a transaction, I hope it has it. The default is apparently an automatic TX fee set by wallet based on something... Probably it does it based on current mempool size..., but how could it know how urgent my specific transaction actually is..? I may want to manually specify more (or less) than it offers, as only I may know if its urgent or not...

Check out Tools > preference
it has lots of options that may answer all your questions, you can check the box for setting the fees manually, in the transaction tab you can check whether or not use change address,...

One additional question - is there a way to disable the automatic address rotating? I mean the behaviour of wallet generating a new address every time I send funds out? I know it is for privacy, but its a bit annoying. Not a deal-breaker, but I would prefer to generate and use a couple of fixed BTC addresses. I may want to refresh them once in a while, but not as often as wallet tries to force me to...

press Ctrl+A
that will show you the tab containing all your addresses, you can label them and use any of them you want, as many times as you want.
read this too: https://en.bitcoin.it/wiki/Address_reuse to understand why the wallet is suggesting a new address each time.

also there is a tab called "Coins" (version 2.7.17) that you can manually select which coins (transaction outputs) to spend.
