I've used two different brands of epoxy for this kind of work.
Used correctly, they are first rate.
They have to be mixed exactly and applied with care.

The wood has to be dry. That takes time.

We used some on an exterior wood coulumn and didn't account for water
penetration above the fix. The epoxy trapped the water in the column.

One worker got creative with the proportions and ruined one job.
I would use the consolidant and the filler from the same company.
