For the last few years (and especially since the pandemic began), my most regular practice has been the Liturgy of the Hours, particularly Lauds and Vespers, which are the morning and evening prayers of the Roman Catholic Church. Each one is two psalms and a canticle, followed by a short reading, another canticle (the Benedictus in the morning and the Magnificat in the evening), intercessions, an Our Father, and a concluding prayer. I have been trying to pray Matins more regularly as well (also called the Office of Readings), which is three psalms followed by a longer reading from the Bible and reading from one of the Church Fathers.

I have found praying the rosary beneficial as well since it is more meditative than the Liturgy of the Hours, but I haven't yet been able to regularly work into my schedule.
