I just noticed that two-wire intercom systems could also be an option since power is available at the gate. However, the cable comes out in the utility room. Is there a portable screen version of the two-wire intercom systems?

You could build something like this with a Gira TKS system. Two-wire video intercom outside, TKS + TKS-IP gateway inside, and an end device (e.g., tablet or smartphone) connected via Wi-Fi indoors. Note: Very expensive. I’m not sure if there are any cheap solutions. Staying entirely on IP-based systems will probably be more cost-effective in the end.

The 2-wire to Ethernet converters are exactly the right solution, but unfortunately they are significantly more expensive (even renkforce at Conrad costs 170 EUR for 2 end units) than either switching directly to a 2-wire system or simply running another Ethernet cable.

In my opinion, two-wire systems are nowadays nothing more than an emergency solution.

I asked around in the electrician forum and also consulted with local electricians; the cable is sufficient for an intercom system with audio, video, and door opener. I will also install a separate Cat7 installation cable as an option for a different video system (PoE with connection to smart home or similar). The telecom company charges a flat fee of 800 EUR anyway, so they might as well dig and lay the cable themselves.

I'm quite sure that your estimated flat rate of 800€ won’t be enough. As partially mentioned before, that’s just a flat rate for a connection of about 10–15 meters (33–49 feet). (I don’t have the exact details in mind and I’m not at home to check.) Once you go beyond the standard distance, every additional meter (foot) costs extra. I experienced this myself...
Back then, I dug a trench where the city installed the fresh water pipe, the telecom company laid the telephone cable, and the power cable was put in last.
In the end, I had to coordinate the water utility workers and a civil engineering company commissioned by the city so that the lines could be installed almost simultaneously.
I also installed an empty conduit for my own use later if needed...
If you have any more questions, feel free to contact me. I hope I was able to help you a bit.

Currently, I have received feedback that Telekom or their subcontractor will lay the cable up to the house – including over the 30-40 m (100-130 feet) – but not inside the conduit.

There is an ongoing dispute because we have the conduit up to just before the house, but not inside the utility room. We are supposed to handle that part ourselves, which would require renting a mini excavator again, etc.

Now the planner wants to specify that digging will be necessary, and we should clarify this directly with the responsible civil engineer through a direct communication channel.
