Only one question, if you dont enforce TCP will it ever go to UDP or something else?

No this is what they say

    /**
     * Protocol for target group, expects TCP, TLS, UDP, or TCP_UDP.
     *
     * @default - inherits the protocol of the listener
     */

So it all depends on listener. And for listener default it TCP:

    /**
     * Protocol for listener, expects TCP, TLS, UDP, or TCP_UDP.
     *
     * @default - TLS if certificates are provided. TCP otherwise.
     */
