A PROJ string cannot carry every EPSG detail (axis order, datum ensemble, transformations). Prefer WKT2 or the EPSG code itself.

Proj4js definition used by the converter

+proj=longlat +datum=NAD83 +no_defs

No datum shift is needed: this CRS is on WGS 84 or a datum Proj4js treats as equivalent at the metre level.
