I'm not sure it would be worthwhile setting up for personal use -- the policies it lets you set aren't doing anything other than ensuring you're following best practices (like setting a screen lock) so you don't gain anything over just doing that, and the direct management tools aren't any finer-grained than you can get from Google's Find My Device.
I'm not sure you're able to set up a linked "for work" profile without MDM; that might be a benefit if you want compartmentalisation.
That said, it might be more straightforward to just use another user on your device
If you have a lot of devices (think 10+) I guess it could be useful to keep them aligned. It could also be useful as training on how to centrally manage devices.
But I would not recommend using a MDM unless you have a specific reason. Personal devices that you have physical control over are easy to manage locally on the device. Adding a MDM also adds another attack vector, if the MDM is compromised all your devices are at risk.
I don't own anything apple, so I'm unlikely to ever run this MDM, but, if a good Android one came to my attention.. maybe? I'm geeky enough to enjoy doing it, even if it comes with no real benefits to me.
I think the major benefit is that this way you control the MDM, and you don't risk that a MDM gets installed on your phone unexpectedly, sort of like a rootkit.

The nice part is I can use the same profile on a Mac too.
