Landscaping for a raised garden bed project

We have a space in backyard we would like levelled off and a base laid, weedmats and aggregate/gravel /sand laid. We would then like raised beds put in place and paths put around. We can supply the raised beds, have neighbour who makes them. We are not sure what the paths should be in terms of tiles/ stones so open t suggestions, have included a couple of photos for inspiration.
