The camera setting with the biggest influence on the shortest possible intervals is Auto Review (this option defines if images are automatically shown on the camera display after each exposure). Therefore I use compressed RAW for time-lapse (and uncompressed RAW for still landscape images). The quality of compressed RAW files is in my opinion sufficient for any time-lapse application and the smaller file sizes are very welcome. uncompressed RAW has no real influence on the possible intervals. It seems that also the choice between compressed RAW vs.

For the test results below a SanDisk Extreme Pro 512GB UHS I SD card with 170MB/s was used.
I’ve tested different SD cards (all SanDisk of different generations and speeds) with the A7SII and found no significant influence of the SD card on the possible intervals with this camera. For example, if you shoot with the A7RII 100 time-lapse sequences of 1000 images each in uncompressed RAW, you get about 10 TB of data, which is not easy to handle (and back-up) if you are on the road.

The big advantage of the Sony A7SII (besides its small size, good dynamic range, and high ISO performance) is, that the file size of the images is quite small (due to the 12MP sensor), which helps a lot if you shoot many time-lapse sequences on longer trips. This test was done with the Sony A7SII camera which is in my opinion very well suited for time-lapse photography, at least if 4K is sufficient for the final output (for 6K or 8K you need different cameras like the Sony A7RII). The camera, the intervalometer and the settings all have a huge influence on the possible intervals and exposure times. Examples are time-lapse sequences of the milky way or in glow worm caves. This is used either to create smooth motion blur (similar to a large shutter angle in filming) or to get more light on the sensor to reduce the noise in night scenes. In many situations, it’s important to use the longest possible exposure time within a defined interval (or the shortest possible interval for a defined long exposure time). Examples are Northern Lights, fast-moving clouds, urban scenarios with moving people, shots from fast-moving vehicles, or when you use longer focal length lenses (since this amplifies the movement). In situations with fast-moving subjects, short intervals are often recommended for aesthetic reasons. For time-lapse photography, it’s very important to know which intervals are possible with your equipment.
