Those are all completely different charisms.
I repeat, it’s important to discern which charism and rule one wants to live under. Benedictines attach a particular importance to the liturgy (especially the Divine Office) because of the Rule. What that means is that in general, whether OF or EF, in Latin or the vernacular, the liturgy will be celebrated with care.
But what really makes the community tick is its faithfulness to the Rule of Saint Benedict in its entirety, not just the parts pertaining to liturgy (the Rule mentions nothing about the Mass, incidentally other than a few passages about admitting/ordaining priests for the “service at the altar”, but has a lot to say about the Divine Office).
Again, if one seeks a vocation on the basis of “tradition”, it has to be the particular tradition and charism of the order. A Benedictine community can celebrate the OF in the vernacular and be completely faithful to Benedictine tradition while another one celebrating in the EF may not. Of course the reverse may also be true.
The discernment process may of course involve looking at different orders, but to determine if one fits with, first the order’s charism, second, the specific community, and third, if one prepared to spend one’s entire life living under that rule. It’s not unlike finding a spouse. If one sticks to superficiality and appearances, one will be sorely disappointed. However in a monastic community, it won’t just be the postulant checking out the community. The community will also check out the postulant. Remember that a community gets to vote on whether a postulant can make each step from postulant, to simple vows, to solemn (lifetime) vows. Someone who is there for the wrong reasons will be quickly found out and won’t even be admitted.
One would think however that someone will first study what each of the orders are all about and then at least narrow down the choices. For example someone attracted to the spirituality of Saint Benedict, may want to check out Benedictines, Cistercians (common observance) and Trappists. Many communities offer the opportunity to live and work with the community for a short period to get to know the order and community better.
