But you’ll struggle to lay mesh in a 50mm screed and get it nicely in the middle without it lying on the bottom and popping out of the top. The initial shrinkage is the big issue on a slab this thin.

It would work. To get the same strength you need to alter the proportions of the other ingredients. There is guidance but it’s a screed, not structural, so don’t know what strength you should be aiming for off the top of my head.

As the screed will be (should be ) quite dry, its relatively easy to position the mesh and it will stay in place not float around. It won't need to be dead centre
But it may be easier for a DIYer to throw some fibres into the mix than have to source, cut, position, tie, and support D49 mesh...

i’d stick to concrete. do it in 3 smaller shuttered sections .
soak each section with sbr before pouring and you shouldnt need to worry about bond or strength or shrinkage. they’re talking sh!t. 50mm concrete from all in with a 1” chipping @ 5:1 will be more than strong enough for what you need without mesh or fibres.
