WIX is extremely limited in every which way, that’s just how it is. It’s better than nothing I guess.
You can get backlinks, do minimal content edits… maybe thats enough for your business. I couldn’t suggest much more without knowing the basics niche, service area, size of the company etc.
My suspicion is if agencies are quoting 5k a month and a website rebuild you’re making life very hard for yourselves by sticking with WIX for no good reason… other website CMS have options to simply upload images to… a clever Web dev, could even make your fellow employees their own admin panel that’s just 1 option to drag and drop images to upload or however you may wish to do it.
