The concept of the internet (IPv4 and IPv6) is that every device has an
unique address that is reachable from any other node. NAT and all that
crap are just temporary solutions for keeping IPv4 alive. We should
switch to IPv6 ASAP.

True.

Then don't let that services listen on your public IPv6 address. For
that purpose you can use an IPv6 ULA prefix that is not routed in the
internet.

I recommend getting rid of devices you can't control. Do you have the
control or the manufacturer?
Think about this.

Use nmap from other devices to check if they respond on any UDP or TCP
port. If so, switch these services off or configure them properly.

Randomly finding them with their IPv6 address is also a PITA.
Mostly you have a /64 net and they either use EUI64 with their MAC
address or privacy extensions with a randomly generated host identifier
(also 64 bits).
Randomly finding such an address is very seldom.
If you want security here run an SPI firewall and only allow traffic
from outside for specific ports (but allow ICMP all the time for Path
MTU discovery).
