If you have the money, the Pixel Stand is fantastic. My Pixel 3’s charge port broke, and at the time the wireless chargers available weren’t quite as fast as the Stand, IIRC. I found one on Amazon Warehouse for like $10 more than other wireless chargers.
You can set it up to do stuff, but my favorite feature is that it has my phone act as a photo frame while charging. I selected an album to choose photos from and it shows me pictures of my kid all day, 10/10.
I’ve been on Linux desktop (Mint) for over a decade now. My company uses O365 for email, as did the organization before them.
I use Thunderbird with several add-ons: Mailbox Alert, Owl for Exchange (paid), Provider for Exchange ActiveSync, and TbSync. I honestly couldn’t tell you which one or ones I find most useful - it’s been so long since I’ve installed them, I don’t remember which addon provides which functionality. My most recent install was Owl, for calendaring and because things got a wee bit fucky with O365 servers for a week or two last year. I have Thunderbird set to collect addresses when I reply to users. You can have it query AD for contacts, I think, but it tends to be a wee bit slow.
On my Android phone, I use the default Google Calendar app, and the Gmail app to query O365.
