Yes.
You can count on your chicken having salmonella in varying degrees. Fresher stuff just a little bit, can be easily washed off and what's left killed by proper cooking. As I recall salmonella produces hydrogen sulfide which helps makes rotten chicken smell like rotten chicken. If it smells bad, it is bad. So when cooking chicken, and turkey or other poultry, for that matter, assume it is infected, clean accordingly. How many times have you used dirty chicken hands to work the sink faucet, turn the stove knobs, open the oven or fridge door ...
Beef, though, is a different story, for the most part. Treat mass produced, commercial ground beef with a wary eye, cook that crap to death. I'd trust it less than chicken. Grind/chop your own, if you can.
Fresh, whole cuts of beef, however, are a different story. Most of then can be eaten raw, if so desired, but your jaw would get pretty tired working on a pound or two of raw chuck cross rib roast. And you'd need a box of toothpicks. Some cuts like tenderloin and top block sirloin can be used for steak tartare and carpaccio, no problem. Most of the cuts from the chuck primal should be braised as a pot roast, but that's a different thread. No need to blow around a lot of hot air on that topic here. And for a smoked beef brisket, 165 is just getting started, possibly not even to the stall point yet, take that pup to 195 - 200. Again, a different topic.
Good steaks, in my opinion, would be ruined if taken to 165F. I like it on the rare side, around 125 or so. Depending on your preferences you may want to go 140, 145, maybe 150 for medium rare or medium.
As far as only searing on the stovetop, it depends on the thickness of the steak. Usually cuts under an inch thick can be adequately prepared using just a pan on a burner. Larger, thicker cuts benefit from pan searing and then finishing in a hot oven. Either way, show some patience and let the meat rest for at least 5 minutes, maybe 10 while you finish preparing and plating the sides or the sauce if you're doing one. You can toss a bit of foil over the meat to help retain some heat, you want it to rest, not freeze to death. Don't wrap it tightly, that will have a detrimental effect on the nice, brown crust you should have gotten from the initial searing.
