Enduro tires

Does anyone have any suggestions for what tires to get? I want them to be decent on the road, but still trail rideable. The tire sizes are - rear 4.00-18* front 3.00-21. Going on a 1970 bultaco matador. The ones on it now are pretty much original.

I know a place in Batavia to mount them (that’s where the bike is currently) so my plan was order, acquire, ride out with my wife and tires, ride it to the shop, have them mounted.

Suggestions would be great, as I really don’t want to just go there and take their word for it

Thanks
