I would stay bedside as long as you physically and emotionally can. Bank the extra $ and leave before you get too jaded. Then move to an educational or case manager position where students and/or patients can benefit from your knowledge and experience. You can physically work it up to (or even possibly beyond) retirement age.
Why not both? There are a fair bit of positions that allow a certain degree of patient sided work. And of course there is always Freelance/Locum work in most countries.
I have switched to a full off-patient role a long time ago and since the beginning of Covid I have worked mostly remotely. But I am still working as a Freelancer for a few shifts per month, depending on my workload.
And I like this model a lot.
You have to figure it out somehow. Just figure out which you could stand doing for a year. You can always try to change to the other after a year if you hate it
Talk to your employer about taking on the role on a “fixed term” basis of say 6 months. Tell them honestly why and see what they say. If you’re concerned about the lack in money see if you can take the 9 to 5 and supplement with the odd Sunday shift back on the floor to prop the wages up if that suits you.
