Right now I have 3 platforms to use (last one is still in shipping) as an mcu for a mouse.

Left one is ESP32-C3 module (RISC-V single-core, Wi-Fi and Bluetooth 5.0, no USB support) with >30mA BLE-tx.
Right one is Ai-Thinker PB-03 (PHY6252 based, Bluetooth 5.2, no USB support) with ~10mA BLE-tx (only repo I have found about it).
And Seeed XIAO BLE module (nRF52840 based, Bluetooth 5.0, NFC, ZigBee, USB, on-board li-ion charger ic) with 4.8mA peak BLE-tx.

Last one seems best for mouse use-case with native BLE/USB support and low power consumption.

Designed and printed a prop guard for my baby quad (for safe indoor flying)
It's not ideal, need to add additional stiffening ribs.

Sent a camera back to seller for exchange. Something was happened with camera at start of april. It's getting colourful stripes on top of a display with rising of module temperature (about 3 minutes after turn on and shit happens). Looks like some crystal oscillator make glitches at overheating.
