A REIT can also be a qualified opportunity business (QOZB), so long as it meet all of the tests. There's nothing incompatible between the two regimes. However, the principal benefits of a REIT may not be useful to a typical opportunity zone investor. One such benefit is that a REIT is a publicly traded entity with a single layer of taxation. However, any REIT shares that a qualified opportunity fund (QOF) acquires on the open market (or otherwise from a third person) will not be "good" qualified opportunity zone property. The QOF must acquire the REIT shares at their original issuance. A REIT is also useful for helping tax-exempt organizations avoid the recognition of unrelated business taxable income (UBTI), but a tax-exempt organization typically would get no benefit from investing in a QOF.
