Ultimately the decision is up to you, but chiming in with what I'd likely do.
The beds sound like they're in an ideal location and produced for you last year, so I'd probably plant in them this year as I'm assuming you're gardening season has already started or is very near. You can observe the individual bed frames during the season and determine which, if any, are worth keeping. If you do decide to keep the frames, you can indeed plant cover crops in each.
If you decide to eventually do away with the beds, you will at least have a harvest this year. You'll need to determine whether to remove the bed soil or smooth it out over the area where you'll be planting cover crops. You could even do a 50/50 by removing half of the beds and sowing a cover crop on the area without beds this year.
Both of my current raised bed garden areas are located where a driveway previously was and the raised beds have been a lifesaver. I did "temporarily" plant a few small clumps of rhubarb in one of those beds the first year and when I removed it last year it was truly a feat as those roots had grown down through the gravel and into the clay below, but boy did they flourish!
