Is this a resonable SPI communication layout? SCK and DATA connected to IC with via. PCB Layout

Question

I am inexperienced. I am worried the traces are too long.
And I worry about the high frequency SPI lines.
I worry that they might cause emi not work properly.

So, is this PCB layout reasonable?

I have SCK and Data lines highlighted in green.
The other lines are mostly chip select lines.
The traces are a bit thick 0.4mm because of physical durability concerns. The sensors are on the red side.
Both sides have a ground plane.
3.3v logic. 8Mhz clock. On the blue side is one esp32 s3 collecting data and sending it back out to a second stacked esp32 s3.
Cropped out is a two row button matrix and argb to match.

The whole cycle is ~600 Milliseconds

1. trigger sensors to start collecting.
2. send old sensor data over spi to second stacked esp32.
3. Write 1 or 2 lines to oled Display
4. trigger sensors to return their data

if it matters this is the sensor https://www.lcsc.com/product-detail/Position-Sensors_Infineon-Technologies-TLE5012BE1000_C123083.html

Basically what I am asking is, does this PCB look sketchy or reasonable?

If you are worried that the tracks are too long why not squeeze all the chips up a bit. I say a bit but, there's loads of squeezing you can do from what I can see. I reckon you could reduce the overall length down to less than half without any real effort.

Keep a full ground plane on one side rather than a badly compromised ground plane on two sides.
