Best Practices for Managing 2.4GHz and 5.0GHz Bands?

I work for a small business and we just have one SSID for production and one for guest\IOT that allow both 2.4 and 5.0. Most all our devices are 5.0 capable, just a few random things that are only 2.4 capable.

The problem is that we recently started deploy Surface Pro laptops and they are frequently connecting on 2.4, and the 2.4 in our area is crap. We have lots of neighbors and sometimes the 2.4 band gets maybe 2-10 Mbps. 5.0 easily gets a couple hundred Mbps. We have a dozen or more different laptop models and whenever I audit which devices are connecting on 2.4 the only Windows 10 devices are Surface Pros.

From what I found the Surface Pro issue is common and there's not a end user device solution other than to disable 2.4, but I'm sure a lot of users have only 2.4 at home so that is not an option. The only other solution that I can think of is to create a new production SSID that allows 5.0 only. Not counting user training issues, what are the pros and cons of doing that? Or is there some other way to force a Win 10 computer to use 5ghz whenever possible? Our APs are Aruba IAPs.
