How to enable easy front-end editing?

Hi guys
I’ve purchased a resume theme, intended to let my digitalscot.net community members have a nice looking, dedicated sub-site. See:

As far as I’ve figured out so far, you use Elementor to edit the resume content, which works ok, but my concern is this requires a much more technical level of access than I’d like. Elementor lets you change/add lots of web level stuff etc.
So my question is do you have any good ideas for how to lock this down and enable a much simpler front-end editing approach. ie only have access to edit the resume content and nothing else, no WordPress back-end options, etc.
I have enabled Support Access if you’d like to log in and have a play around.
Many thanks, Neil.
