Gaia Data Release 3 (DR3) provides >181 000 radial velocity (RV) solutions for single-lined spectroscopic binaries (SB1s) that can be used to search for non-interacting compact object + star binary candidates by selecting systems with large mass functions. We selected 234 such systems and identified 115 systems with good RV solutions in DR3. We used light curves from the All-Sky Automated Survey for SuperNovae (ASAS-SN) and the Transiting Exoplanet Survey Satellite (TESS) to identify and remove 31 eclipsing binaries to produce a catalogue of 80 compact object + star candidates, including 38 ellipsoidal variables. The positions of these candidates on Gaia and Two Micron All-Sky Survey (2MASS) colour-magnitude diagrams (CMDs) suggest that many of these systems are binaries with luminous companions. We compared the periods and eccentricities of detached eclipsing binaries in Gaia DR3 and ASAS-SN, and found that ${\sim }11 {{\ \rm per\ cent}}$ and ${\sim }60 {{\ \rm per\ cent}}$ of the binaries had different periods and eccentricities. We also compared RV solutions for 311 binaries in both Gaia DR3 and the Ninth Catalogue of Spectroscopic Binary Orbits (SB9), and found similar results. We do not identify any strong candidates for non-interacting compact object + star binaries.
