Then DNG is ideal for your purpose.

There are no restrictions on who can develop software that uses DNG. It is the only genuine archival raw file format that currently exists. (Because it is openly specified).

DNG contains extra metadata that described the sensor configuration and characteristics in more detail that CR2s and NEFs do. (That is why users of DNG don't need to upgrade their raw converters for extra camera models). So your future software of choice doesn't have to recognise the camera model (D1234 or 5678D) then have a look-up table of the camera details.

The required camera details are in each DNG, so software can process DNGs from unfamiliar cameras.

This will avoid a problem that you may otherwise encounter in future. Someone may develop a new software product in years to come that has all the features you want, but doesn't support all historical cameras. It doesn't matter with DNG, because it isn't necessary for software to recognise the camera model in order to support the DNG. But software typically DOES need to recognise the camera model when reading NEFs and CR2s, because they don't contain all the metadata needed.
