I found disabling aes ciphers alone killed 90% of the bots with an occasional ECC only bot sneaking through. I only have 2-3 options for MAC, KEX and cipher. Certain mobile clients won't work (older embedded ssh library) but others support more modern configs. But I started my journey with [1] and have slowly tweaked and slimmed it down over the years.
