Thank you very much 
I’ve found that Doks Ghost is well-suited for my needs. Without your input, I would have never considered exploring other options.
I’ve checked out Landing page - Doks and it looks promising.
Regarding self-hosting, does magicpages.co offer the option to choose server location? Or do they provide management for a Ghost server? I’m quite impressed with their offerings. I believe that using Ghost with Cloudflare and MagicPages.co could potentially resolve all the loading issues.
I’m unsure about the duration of the migration process. I have nearly 1400 pages, all of which are manual and static WordPress pages with HTML blocks.I plan to test the migration on a local environment with a dummy domain to anticipate any challenges I might encounter.
Considering the upcoming holiday season, I’m looking for reasons to expedite the migration process. 
Advance Happy Holidays!
