Which mikrotik can be selected for wide Wi-Fi coverage?

Question

WiFi

Tell me, please, which microtics (or something else reliable) can be selected to solve such a problem:
1. the provider's cable enters the room from the bottom right (see the diagram) and cannot be moved
2. it is impossible to reach the cable to each access point from the central one
3. Access points 3 and 2 can be connected with a cable.
4. from points 3 and 2, only 3 can be powered from the network, therefore, etc. 2 can only be powered by PoE
5. there are 2 walls with a thickness of about 70 cm
6. "communication" between points 2 and 1 is possible only over the air
7. etc. should drop clients if their signal level is low (a la roaming/zero handoff, etc.)
8. The distance between 2 and 3 is about 10 meters, the distance between 1 and 2 is about 2-3 meters, the main customers are to the left, etc. 3 and to the right, etc. 2 (up to 6-7 clients in total)
9. etc. 3 and 2 can NOT be moved.
10. budget 14,000 - 18,000 rubles.
11. There is a time limit, so rare "exotics" are not approved (the solution is being implemented in remote areas)
Other questions:
1. How much does the speed drop when using WDS? Interested in the opinion of those who have applied solutions with WDS in practice.
2. What alternatives to Mikrotiks can be used? (sufficient for long unattended operation)
