Personally, I set IdentitiesOnly yes as the global default in ~/.ssh/config, and explicitly set the preferred key separately for groups of hosts. All my keys are under ~/.ssh/keys or ~/.ssh/sk so they don't get automatically picked up by the client when a host hasn't been defined yet.

The client is only cumbersome if you don't use ~/.ssh/config and have never refered to `man ssh_config`.
