When using I2C operations like 'i2c_master_transmit', 'i2c_master_transmit_receive', or 'i2c_master_receive' are there any requirements on the buffers?
Can they be in SPIRAM, or do they need to be internal?

Re: I2C buffer memory requirements
No requirements there. Data is moved to and from the I2C peripheral by the CPU, so data can reside in internal or external RAM, or even in flash.
