What I really like:
23/24
23/91
112/113
23/112
91/112
23 is a good PS for wellbeing, good life in general. 91 is used for protection and also for getting answers to prayers.
112-113, for good life as well, some say 112 is a good financial wellbeing psalm.
Trips.
23/24/91
23/24/112
23/112/113
The psalms 1, 2, 3, 4, 5 are among my favorites as well. Then the PS 20, victory psalm.
For a while I mixed together 25 and 27, it felt quite nice.

65 and 72 are also good.
68 and 69 together. They are a bit longer but very nice effects.

A mix containing 100 and 150, they sound like excellent praises.
With 150 there are so many possible ways to combine them together.
I like 118 and 119, as double or mixed with 23, 91, 112, 113.
To keep it simple I think a good idea is to focus on let's say 2 or 3 PS together. Maybe pick 2 and focus on them. There are all kinds of systems, prayer rules. Somebody might read them 7x a day, or 3x a day, maybe even 12x.
Focus on the chosen psalms and add some random ones in there, adding some variety, making it more interesting.
