Maybe you didn't uninstall connman? It has a default setup to use DHCP
for the Ethernet cable, and that's presumably what is helpful here.

According to the connmanctl man page you may reconfigure connman
either to ignore eth0 (which it calls Ethernet_46ea672351_cable, or
something like that), or to use static IP for it.

As far as I can gather, connman calls it a "service", and you would
inspect current operational state with "connmanctl services", followed
by "connmanct services Ethernet_46ea672351_cable" to hone in on its
setup for eth0 (note the name).

Then there is the alternative of purging connman and stay with
ifupdown; if I were to try to advice you, then that would be it.
