Road bike geometry 🤷‍♂️

So I’m fairly up in my geometry mtb wise and happy with both my bikes. On the road bike front I’ve always been pretty happy with my Cannondale caad12 disc (54cm size) - although I’ve run it as it came new with all the spacers under the stem - but with the angle of the stem down rather than up. I’ve also always been a bit annoyed it doesn’t have mounts for proper mudguards. Up sides are it’s pretty light (1150g frame I think), handles nice and snappy and fun cornering for a road bike. Mines got Ultegra di2 and Hunt 4 seasons road wheels. With a recent back spasm it’s a bit on the low side at the front and have flipped the stem to point upwards which is better - but it looks daft. So I’d like to pick up a new frame that does the following: Higher front end Still light - looking for frame only 1200g or less Mudguard mounts Discs Bolt through axles Not devastatingly expensive (£1500 max for the frameset if I can use cycle 2 work vouchers) About all I’ve been able to find that might fit the bill is the Ribble Endurance SL. Frameset only is £1400 - pretty much any other frameset I get will mean new cranks (as I have stupid bb30a) and a new front caliper as mine is post mount front / flat mount rear. The headtube is 11mm taller and weight should be similar. It has mudguard mounts and looks pretty nice. I went into Ribble today to have a look at one and was hoping to get a sit on it. But apparently they don’t do that - you have to sit on a seperate jig (even though they had a medium of the bike I want literally in the shop) and someone was about to start a fitting on it. I had my 5 year old with me so no way she was going to wait for it to be free and whilst I got on. Very frustrating. The guy in the shop said I might actually be better with their R872 as it’s more relaxed geometry again than the endurance sl. It doesn’t look quite as nice and doesn’t come frameset only - but could buy the basic tiagra one for £1500 and flog the bits I don’t need - might fund the cranks and a chunk towards some carbon wheels. The below link should go to a geometry geek comparison of the caad / R872 / endurance sl. I stuck in the snallnof each but I think it’s medium I’d want. Any thoughts on the options would be much appreciated. I assume stack is made up of wheelsize / fork length / head tube length?

My smooth brain finds bikeinsights.com easier for comparing geometries, pictures rather than numbers...
