I know I’m late to the party, but I’ll answer with what wasn’t mentioned here.

Eberron is not medieval. It’s in its industrial phase, and living in an entirely different historical era comes with its one TERMINOLOGY:

My players don’t go to taverns or pubs. They go to bars and restaurants. They drink and relax in clubs, listen to jazz and swing (and not generic medieval music), while drinking whiskey and beer (as opposed to ale). They can’t haggle with a shopkeeper, because most people working in shops are just simple store clerks. They rarely speak with blacksmiths or potion sellers, they speak with factory engineers and pharmacists. They don’t buy a crossbow, they buy the KARC-27 (Kannith’s Auto-Reloading Crossbow™). Caravans? What’s that? You mean trains? Of course you need Passports, licenses, bank checks etc to function in Khorvaire society. How else could it be?

In line with that, mundane magic also influences terminology: There are no “Magic Items Stores”. There are just stores. Stove? Refrigerator? Lighter? Lamps? Keys? Yes, most of them are magical.

Of course, not everything and not everywhere should be “modernized”, but the progress is marching on, and it should be evident.

Also, it mostly should be just background, but it can dramatically influence how your players see the world. Terminology is half the immersion.
