Thank you all, for your help.
Just to confirm, I took my bike with MTB V-brakes with road shifters for their first long ride on a flat track. The brakes stop relatively well however they definitely lack the sharpness of hydraulic brakes on my other bike, not sure if I can trust them for emergency braking.
I will try TRP Spyre/Tektro C550, they might not be as good as hydraulics but I hope to see the improvement from the shorter pull.
