I say you should go full manual and get one of the laowa lens like:
https://www.amazon.com/Laowa-100mm-2-8-Ultra-Macro/dp/B07RML2CK7/ref=sr_1_1?dchild=1&keywords=laowa+100mm+f%2F2.8+2x+ultra+macro+apo+canon&qid=1605340902&sr=8-1
or this one:

They don’t have autofocus but it is better to do macro shoot with manual focus anyway. They don’t have stabilization though.
These will go to 2:1, which are twice the magnification of the tamron.
