Does anyone have any favorite mobile tech sites they want me to look at while I'm considering the next phase of mobile redesign?

My idea is to build a new mobile design without using any forum framework (do not use vBulletin, XenForo, etc.) and do not use any big SPA Javascript frameworks (do not use Angular, Vue, React), and not to use any cookie-cutter CMS (no WordPress, Joomla, etc.). These cookie-cutter frameworks seem so boring.

So my initial idea is to use the basics:

and avoid like the plague (do not use):

The reasons for this is that we have a perfectly good DB already and the back end is not really public facing, so there is no reason to worry about the back end.

As far as the UI, there is nothing really interesting to be gained by cookie-cutter CMS and my experience this year with Vue (big JS SPA frameworks) was that

So, the new mobile design would be mainly just writing some JSON AJAX queries and displaying some nice mobile UI, with responsive modules which can go "anywhere on the site" , maybe with infinite scrolling and some bare-bones JS libs.

I thought I would design a new home page for mobile first; and the move on from there. I'm just not keen on "frameworks" these days, I guess. I enjoyed building the UserCP with VueJS, but I would not do it again if I had to do it over again. The more experience I have will full-stack web development, the more I am disappointed with "frameworks" and cookie-cutter CMS software.

My idea is "everything is a responsive UI module"; and "no dependance on frameworks".

Any ideas or suggestions ?

(please don't suggest any forum packages or CMS-like frameworks)
