  "abstract": "We present the \\epochstwo\\ sample of $2452$ star forming galaxies at $6.5<z_{\\rm phot}<16.5$ produced using the \\galfind\\ photometric pipeline across $\\sim650-740~\\mathrm{arcmin}^2$ in six of the most widely used deep, blank field \\jwst/NIRCam imaging surveys. $293$ galaxies are spectroscopically confirmed and a spectroscopic--photometric redshift comparison yields a normalized median absolute deviation, $σ_{\\rm NMAD}=0.017$, an $η=4.3\\%$ outlier rate, and a mean offset $\\langleΔz\\rangle=-0.022$. We find $34$ little red dots (LRDs) with ``V--shaped'' SEDs, as well as $69$ L--type, $36$ T--type, and $2$ compact Y--type brown dwarf candidates, which we remove from our sample. The fiducial sample yields a flattening $β_{\\rm UV}-M_{\\rm UV}$ relation with only moderately blue median $β_{\\rm UV}(M_{\\rm UV}=-19)=-2.32^{+0.08}_{-0.07}$ at $z\\simeq12.5$, implying dust-polluted stellar populations at the highest redshifts. A ``gold'' sample of $62$ sources are identified at $z_{\\rm phot}>10.5$, $\\sim85\\%$ of which are without NIRSpec follow-up, including $15$ candidates at $z_{\\rm phot}>13.5$ across a diverse range of proper sizes $30\\,\\rm pc\\lesssim r_{\\rm c}\\lesssim1.5\\,\\rm kpc$ and UV slopes $-4.0\\lesssimβ_{\\rm UV}\\lesssim-1.5$. Two very promising candidates stand out, GS-W-4608 and GN-Med-1881, with $β_{\\rm UV}\\lesssim-3$, $\\gtrsim1.6\\,\\rm mag$ \\lya\\ break colors, and F335M and F410M detections which improve their high-redshift solution robustness. Complementary to our high-redshift sample, this public data release provides the community with optical/NIR catalogs, empirical PSFs, and \\eazypy, \\bagpipes, and \\bdfinder\\ SED fitting results, enhancing the legacy value of photometric JWST data in the upcoming era of wide-field imaging datasets with Euclid and Roman.",
