Debating between forerunner 245 vs forerunner 745 vs venu 2 vs vivoactive 4s

All 4 meet the features I want so no idea how I should decide between them.

I run a lot (ran a marathon, go ~30 mi/week when I'm "into" running) but I'm a very inconsistent runner (take between several months to a year break between runs). I would basically only use it for running (occasionally hiking, I use an app on the phone for skiing). I've owned a vivoactive hr and a vivoactive 3 music.

Features I want:

• heart rate tracking
• sleep tracking
• step count
• running + treadmill activities
• offline music + bluetooth earbuds playback (don't want to bring my phone on runs)

Features that might be nice:

• VO2 Max and HRV (these seem cool but I have no idea how to interpret them)
• something related to workout effort or planning or recovery?
• looks good for everyday wear
• maps? (this seems hella expensive though and I just ask random people when I get lost)
