Telecom router with Fritz Mesh Repeater possible?

The situation: We're Telekom customers (Telekom router Speedport Smart2) and have a (very old, very solidly built) house. The telephone connection is located there on the top floor (i.e. In the most unfavorable place in the house). One floor below is the living and dining area (where everything actually happens) and another floor below is an apartment that is also to be supplied with the connection. There's currently a Devolo repeater located there.
That works so mediocre. So the repeater is okay, but sometimes you have to expect Wi-Fi problems. Netflix works, for example, but has to "reload" from time to time. Or the quality decreases for a short time.

To the question:
Would it be useful to replace the Devolo Repeater with a Fritz Mesh Repeater (3000)? And can I even operate the Fritz Repeater with the Smart2 router from Telekom or does the "mesh system" only work in conjunction with the Fritz router?
Would it also be of any use if I set up an additional repeater in the living area (2nd floor)? So that there's a repeater on each floor (or the router on top)?

Unfortunately, I have absolutely no idea about this system, but as it reads in the advertising, it seems to be an option for our company. Because, as I imagine it, the two Fritz repeaters in combination with the router would supply the entire house (all three floors) with Wi-Fi.

Maybe somebody can help me? Or maybe you can recommend a website where you can get all of this explained in a reasonable way? I don't know exactly how to find that out? So which manufacturers are compatible with each other, what effect does the thickness of the house walls and the floors have, etc?

I would be very grateful for constructive answers.

In solid construction, even with old buildings, you simply can't get very far with Wi-Fi. In a multi-storey building (here probably a single family home, possibly with a separate apartment), you usually have to provide at least one WLAN AP for each floor, which in turn has to be connected to the router with a cable. This also means, however, that you either have to be able to use existing conduits or - if these are not available - have new cables run through the whole house. Most of the time, the floors are the problem; in new buildings from the 1970s and 1980s, the partition walls on the floors too, because they are often made of reinforced concrete - and therefore hardly penetrable with Wi-Fi. You can of course plaster the whole house with repeaters, but that does not solve the basic problem: WLAN can only be used to a limited extent in solid house construction.

Somehow the repeater will work.

But why don't you use Telekom's Speed Home Wi-Fi. The you works for me without any problems. And there are even offers where you can test several of them.
