When they make campaign promises, they go to small towns and talk about "Main St" businesses. Not sure why anyone believes them at this point (for the reasons you mention), but it is what they campaign on.

Oh dear. They make those statements for the benefit of people who don't own small businesses, but are "low information voters".

That wing of the Republican Party does not exist anymore, they are now centrist Democrats.

I think republicans could get behind some measure of portable health plans between employers. What they could not get behind is universal, in the sense of "everyone living in USA" health care footed by the US Government. The objection would be about centralization of health care funding and about, you know, who would get the benefits.

People of color?

I doubt POC would be the main issue. I do think immigration status would be front and center. They do overlap, but not entirely.

They used to be, before Trump and the MAGA clowns destroyed the party. So prior to 2015 or so.
