[ARMA: CWA Remastered] Need help with a few things

I'm playing the remastered version for the first time, after many years I haven't touched OFP/CWA as a whole. Gotta say, it's great coming back to it.

That said, I need help with a few things:

Firstly, even for a remaster, I hoped they'd also improve the controls scheme and make them a bit more modern, considering how badly they aged and remain unintuitive. Changing the keybinds also remains unintuitive. I've already made a few changes. It's playable, but not great. Question: is there a mod or a guide out there that helps turn the controls to make them resemble more of the later titles?

Secondly, I'm currently replaying the Resistance campaign, and have reached the mission "Hostages". In the previous mission, "First Strike", it ended with me being injured. The same condition got carried over to "Hostages", so now I begin the mission already injured. I'm 99% certain this never happened in the legacy version, because it doesn't make sense to start a new mission injured. However, in the missions before those two, I started fully healed. Question: is this intentional or a screw-up of the new update? I know I can revert "First Strike" and play it again more "carefully", but I guess the same issue could happen again.

Thirdly, asking generally: any QoL tips I should know about specifically with the remastered? Also, what would be the best source for updated mods compatible with the new version?

I appreciate the help.
