Is Mobile redirect still viable or are their penalties?

I am just wondering if there is any penalty for a mobile redirect.

The genesis of this question revolves around my website, which is mobile friendly, fast and responsive. It scores well in all aspects with just a few WordPress inspired hitches.

The down side of minifying and moving javascript CSS et al to get the speed I wanted is that many of the plug ins I would like to use glitch up. I am not willing to give up the speed for most of them but one is really cooking my cookies

In order to get my site to score well on both the mobile and the desktop scores, some compromises in design aesthetics were made. resulting in a Mobile site I am very happy with and a desktop site that is just a little dull and not as attention grabbing as I would like.

One tool/plugin I would really like to use is a table stacking responsive tool, that will stack my columns for  mobile use ( so that on the desk top I am three wide and on the mobile I am one wide)  But with the optimization of minifying and moving scripts to the bottom to gain speed, the tool I had (and the others I found) no longer work)

So my question is (TL|DR) is there a penalty for forwarding your home page to a mobile version in speed or SEO function (because my last solution to get what I want is a separate mobile page but I don't want to screw myself over aesthetics)

Alternatively if you know of a table stacking plug in, html/css code or other work around that would be great too

And yes I am old school, I still use tables and do not use Gutenberg or block editing
