Can DNS over HTTPS or DNS over TLS do any difference in routing?

As far as I understand, changing the DNS protocol to DoH or DoT doesn't directly impact routing. However, it's worth considering your DNS provider, if your nearest server doesn't support DoH or DoT, there might be some routing implications. It is less likely to happen with major providers.

No, there is absolutely no impact, routing does not depend on application layer.
The only difference is the port, i.e., 853 for DoT and 443 for DoH.

So use whatever you want.
From anonymity perspective, DoH is better.
From network administrator perspective (i.e. control and monitor) DoT is better.
