What works for you is what works for you.
This just came to mind......Have you ever tried using the Beat Scanner? Instead of tapping - hold the tap button and strum your tempo. It *will* show the tempo on screen as you're entering that way. I find that WAY better than the traditional tap-tempo. You can set it to mute the signal so your strumming isn't heard.
The only other suggestion I have would be to use something like this: https://www.disasterareadesigns.com/shop/p/micro-clock
Yeah I like beat scanner, but would still like to see the BPM on the screen. That's what my Future Factory delay does, I tap in and I see the BPM on the display. Just old habits. I thought it wouldn't be too hard to develop that kind of thing but maybe it is.
