Given the ability to be in constant contact with satellites and whatnot, can’t we just have the black box data uploaded in real time and do away with the search for the box after a crash? Are there so many flights that there wouldn’t be enough bandwidth?

What happens if your data uplink gets damaged? Black Box data is only useful when things go wrong.

Couldn’t we do both? Have the uplink and, if it’s disrupted, then go to the box?

Fairly sure we do. There's at least some info that gets sent to the ground in realtime.

Mentor pilot did a video on that, iirc it's just too much data + ridiculous rarity of the accidents, these factors make uploading too impractical

ICAO GADSS recommendation. A certain part of this idea is being implemented but it's very costly and will take time. Of the big nations, EASA is taking the lead, with a new aircraft of 27000kg+ mandate to have these systems installed by Jan 1, 2025.
To my knowledge existing aircraft won't be retrofit, but I could be mistaken. At least, not any time soon.
The industry is constantly studying and recommending new regulations and standards, it's just always a balance of feasibility, cost and the incremental safety increase.

That is actually required per the current standards.
You have both a relatively low telemetry rate that is transmitted via either satellite radio or ground radio, and a higher rate data stream that is recorded locally
