I have a need to fit a sump and pump, i'm expecting space inside to be too limited for one of the standard float switches to work.
What i feel like i need is a fixed float sensor/switch mounted to the lid or wall of the sump so that it just runs vertically. Or something like a cistern ball float valve with integrated switch.

Anything like this on the market?

Hi
Loads in the marine industry.
 Worth a look at bilge pump float switches. Most are classed as DC. Check the specs and if not sure just add a relay.
They do small float switches and if there is room for a pump there will normally be room for a float switch.

This type but many others.

Maybe a complete wastewater pump station ,  is doing  the sump and pump in one go ??  Fair priced as well

Try ABS pumps, the link I provided last week to another thread is similar to mine, the float switch is integral to the pump body, not a separate unit. It has a selector switch for manual or auto.

Is this the sort of thing you mean?
These prices do not see that fair compared to the component parts?

It's not a cheap way of doing it, but conductivity switches are pretty compact.

For example:

Get a scrap washing machine/ dishwasher -most modern ones have a polystyrene float switch on the btm to cut water if  machine floods.

Keep it simple. Use a pump with a built in float. Less to go wrong

where is it for?

my parents cellar had a sump in it, old house so it was just a hole in the concrete down to the mud underneath

small pumps work way way better than big ones... they're quieter and less hassle... big pumps empty the pit in seconds... but are noisier and tend to dance about a bit starting/stopping

From experience in the small cutting room we have on farm currently, not a lot of liquid daily.

Not far at all, just needs to be lifted high enough to discharge into a waste pipe run on the outside wall

I've used this style of pump for 10 years no issues.
Currently on sale from this supplier.

They do 230 and 110 volts, I have the 110 version.

It has a auto manual selector on the top, with auto pumping down to approx 3mm of the bottom of the pump.

It has a threaded pipe outlet, that means you can use different diameter flexible waste pipe.
Nice and quiet
No connection to company
I try to minimise grief in my life by picking products, appliances that last as I used to work away from home and wanted the wife and kids not to have hassle/ Indidnt want hassle while I was away!

Good luck

I have two of that type but find the float valve on those needs a fair bit of room to work. Hence I was looking for something that worked vertically.
I think I'm sorted
