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.
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.
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.
