What mech to go with these shifters?

[jay clock]

I am overhauling an old Spesh Sirrus, but the bike is at my daughter's for collection and I need to order all the parts in.

It is 8 speed and I have ordered these shifters that are pretty much like the ones on there currently. https://www.ebay.co.uk/itm/Pair-Shi...748205?hash=item4b6b89ec2d:g:BmkAAOSw50BdijkO - what rear mech is compatible? pretty much anything? It is a triple chainset if that helps.

Cassette will be this https://www.wiggle.co.uk/sram-pg850-8-speed-mtb-cassette/

Thanks!

cannot see many 8 speed on offer, assume 9 speed will be ok? Black preferred!

Acera as above, or any similar 8 speed derailleur will work as long as it's medium/long cage.

Acera or similar triple front derailleur.

Alivio rd-m410 is what I've got matched with those shifters.
