Thanks for all the recommendations.
I would also recommend Navigator paper
IMHO, you want at least 80gsm - anything thicker and would suggest checking that your printer can handle it. Navigator paper is meant to be decent - recent deal here.
Canon is really good and a premium paper but prices are all over the place - I bought https://www.amazon.co.uk/gp/product/B08GQ455KC/ this for only £2.50 last week (Prime) and now it's £7.67 per pack (Prime)!
