Some of the supported DEMs are 90 m products. And with oversampling in E-W direction toward the poles in original EPSG:4326 grids, can potentially do better than 30 m. Could just let GDAL compute the appropriate output tr.

Can create a dictionary for each available global DEM dataset and the required vertical datum transformation. For example COP30 requires EGM2008 to WGS84 offset grid: https://github.com/dshean/demcoreg/blob/master/demcoreg/get_refdem.sh#L47
Some of the available Global DEM datasets are already corrected for ellipsoidal heights, specified with the '_E' suffix (e.g. 'SRTMGL1_E')
