  We present a JWST imaging survey with NIRCam and MIRI of NGC 346, the
brightest star-forming region in the Small Magellanic Cloud (SMC). By combining
aperture and point spread function (PSF) photometry of eleven wavelength bands
across these two instruments, we have detected more than 200,000 unique
sources. Using near-infrared (IR) color analysis, we observe various evolved
and young populations, including 196 young stellar objects (YSOs) and pre-main
sequence stars suitable for forthcoming spectroscopic studies. We expand upon
this work, creating mid-IR color-magnitude diagrams and determining color cuts
to identify 833 reddened sources which are YSO candidates. We observe that
these candidate sources are spatially associated with regions of dusty,
filamentary nebulosity. Furthermore, we fit model YSO spectral energy
distributions (SEDs) to a selection of sources with detections across all of
our MIRI bands. We classify with a high degree of confidence 23 YSOs in this
sample and estimate their radii, bolometric temperatures, luminosities, and
masses. We detect YSOs approaching 1 solar mass, the lowest-mass extragalactic
YSOs confirmed to date.
