Is there a good sealant for concrete?
Now that I've done my repair job on my concrete step (with mortar), what is a good sealant to cover the entire step so the elements don't get in and wear away at it over time?

what do you want to achieve ? just protection from elements ? silicone siloxane is a good penetrant

sil siloxane's advantage is that annual resealing isn't necessary,,, being an industrial material, its also more expensive but has great shelf life,,, we have some stuff 3yrs old which still performs well

IF i thought thompson's were better, we'd use it,,, have never seen it spec'd on any fed/state/municipal work yet & i did that work for 30yrs,,, true we do lose some jobs today due to higher mtl costs but that's rare,,, 1/2 of the 1's we do lose have come back shortly,,, i think the other 1/2's too embarrassed to call us,,, i don't think any of our competitors have the breadth of mtl knowledge/methods/equip so that gives us a leg up

Stadry, let's look at who you're talking to.
What you say is absolutely true but does the average DIY want to spend the money on a professional grade material that will also sooner or later need to be redone at some point in time.
Thompson's' and others similar to it are meant for the consumer level. Do a cost comparison. A 5 gal bucket of PS110 Siloxane Water Repellent WB-10 Penetrating Sealer goes for $150.00. Thompson's is $65.00 for a 5 gal bucket. And Thompson's does do a decent job for homeowner use.

I found this fascinating. Here is a scientific study on linseed oil v siloxane. I find the linseed oil an attractive option to consider for a retaining wall because I have it easily available (jugs already in the garage) and application is so easy...paint brush! I'm already saturating wood surfaces with linseed oil, so why not just slap some on concrete too? I haven't yet done this, but after reading this post it gave me the idea: it seem so intriguing.
