Just a note:
The thumb safety on the M&P is not like other pistols. On most guns a manual lever safety blocks the trigger and either disconnects or blocks the sear.

The safety on the M&P only blocks the trigger from moving. It makes no action on the sear at all.

I have one on my M&P 45 because that's all that's sold in CA. Given the choice I probably would not have opted to get it. Still, it's a non-issue. I'm used to a 1911 so, the safety is something I'm used to.

If I were you, I'd get the one with the safety. If you don't like it, you can just take it out. It can be removed easily in about 5 minutes.
