I was exactly the same when I first started using Macs and Alfred was mentioned. I installed it and was completely overwhelmed with what it can do so I went back to just using Spotlight.
I still mainly use it as an app launcher but I also have some custom workflows configured, one called 'boot' which opens all the apps I generally open when I boot my Mac. Another one called 'messages' which opens (you guessed it), Messages, Messenger and WhatsApp. I have some radio applications which, when I use them, I always open them in a specific order with a slight delay in between.
I've got some custom web searches configured for specific sites, my blog, a callsign lookup engine, short wave frequency lookups, etc.
I've also tweaked the default search so if it doesn't find any local results, it searches google but with " -site
interest.*" on the end for obvious reasons.
Alfred can do a lot, even with the things I'm doing, I've barely scratched the surface. I looked at some YouTube guides to show how to do things and it gave me ideas.
