You really don’t want to be using wireless mics because you have the possibility of radio interference (happened to me) and the possibility of interfering with the officiants microphone if they’re also using a wireless mic. It’s much safer (and easier) to use what I said and then you just use a program like PluralEyes to sync it up in post.
As far as low lights conditions, just get a low light lens (f 2.8 or better) and use a video light if necessary. I’ve been using Canon t3i’s my entire career.
