Note that Mikrotik RouterOS before 7.15beta4 requires the fiber to be plugged before allowing ping/telnet/webGUI to the xPON SFP. This will trigger an alarm on the OLT at least on the first config. It is suggested upgrade to 7.15 and activate "Interface/SFP/Ignore Rx LOS", or use a media converter for the first config.

Bridge Mode
Bridge mode allows full HSGMII speed without any major issues and seems to work in mixed mode too.
Positive results in mixed mode with the following hardware:
| Huawei MA5671A | |
|---|---|
| 6COM 6C-SFP-10G-T-Intel | ✅ |
In any case, the use of a DAC or MikroTik S+RJ10 is always recommended.
Router Mode
Unfortunately the CPU will have a major impact on end performance with resulting downlink speed topping at ~700Mbps.
Note that when using Huawei MA5671A with right.com.cn firmware on a Fastweb Italy IPoE connection you may run into some issues since no VLANs are used. The ONT responds to DHCP requests with a 802.1Q tag for VLAN 0, which should be handled by properly bridging the WAN as well. Other providers that do rely on VLANs such as 835 won't probably need to resort to the this workaround.
