Another worm can opened! You will get multiple answers to your question. Regarding sizing, it's probably going to be a try and see approach since cloth glove sizes are not uniform.
I use nitrile (XL) when using acetone. If I need to handle a MS coin, I also use the nitrile. Good tactile feel and provides needed protection. I've never dropped a coin due to the gloves as some suggest might happen. Do any work over a soft surface such as carpet or a towel and you will be fine.
