What sort of riding? Mostly hills, mostly flats? Lots of breaking? Quality of road surfaces?
For me, for the riding I do, at that sort of budget, for a nice set of wheels, I’d be having a good look at these…

Reasonable width, depth, weight. 90kg limit and a moderately low spoke count though so you might want something a bit more robust. Keep the old wheels for when it’s crappy outside.
If you want one set of year round wheels I’d just build some Archetypes on decent hubs (Shimano or DT depending on preference for cartridge or cup and cone.) I’ve got some on Ultegra hubs for my winter wheels and they’re lovely to ride.
But I’d do this first…
To be honest just ride the bike for a while with the current wheels.
TBH I’d change tyres and tubes long before I’d change wheels. Decent open tubs and latex tubes will make a big difference.
