For drop bars, my preferred
compromise is this:
https://www.sjscycles.co.uk/accessories/zefal-cyclop-bar-end-mirror/Fixed on the bar end. It folds back easily when parking the bike. Cheap, and not particularly good optically, but it does the job for me.
I tried something similar to the Mirrycycle, but didn't like the brake hood attachment. The Sprintech wasn't far enough out, obscured by luggage and clothing.
My preferred mirror for
viewing is this B&M:
https://www.sjscycles.co.uk/accessories/busch-muller-cycle-star-mirror-fits-to-handlebar-end-short-stemLess distorsion, bigger and better-shaped mirror. But it isn't designed to fold back and is therefore vulnerable to falls or knocks.

Bike stand - I never bother. Most times there is a wall or vegetation to lean the bike against. When there isn't I lay the bike on its side on the ground.

Locks. On the bikes I use for touring I have ring lock fixed to the frame. This is my short-stay lock for things like toilet stops and popping into a baker's shop.
Complemented by a U lock and thick plastified cable, which I use to attach the bike to something fixed (lamp-post, etc) for longer stops, including supermakets. The Ortleib rear panniers can be secured by threading their wire security loops over the ring lock.
On a lightweight bike for day rides I am careful where I stop. I carry a minimalist cable lock if I don't intend to stop, this is for unplanned short stops. If I intend to have a lunch stop at a restaurant or something else where I leave the bike I carry the U-lock.

Lighting. I have fixed hub dynamo lighting, for my touring bikes two rear dynamo lamps, on the lightweights only one. In both cases a battery powered rear LED lamp as well.

When using hotels and hostels, so far they have always provided somewhere to park the bike. Once or twice I have had to carry it up stairs and put it in the bedroom.
