no problem. i'll post some options. i went through this similar drill a few months ago on our new home build. so fortunately or unfortunately, i had to learn of the latest products. and we had just upgraded our current home's in-wall oven and cooktop as i explored the costs of going down to a single slide in range to replace the in-wall and separate cooktop.
NOTES:
LG is owned and makes named LG branded appliances.
Whirlpool Corporation owns the Jenn-Air, Maytag, Amana, Roper, and KitchenAid brands.
Electrolux company currently owns Frigidaire, Tappan, Kelvinator and Gibson appliance brands.
The appliances division of GE was purchased by the Chinese-owned Haier company in 2016. Four years prior, the same company acquired the New Zealand appliance maker, Fisher & Paykel. When the Haier company acquired GE, they wisely retFromained the right to use GE brand names through 2056. Today, Haier manufactures GE, Hotpoint, Cafe, Profile, and Monogram branded household appliances.
Samsung owns and makes Samsung. In the summer of 2016, Samsung acquired the Dacor brand of American-made luxury appliances.
So you can see your choices are pretty clear. different brands will have different warranties and might share some parts. Example, KitchenAid's warranty is stronger and longer than Whirlpool. But Jenn-Air is longer and covers more than KitchenAid's warranty. But the parts shared between KA and Jenn-Air are nearly identical on cooktops sans some "beauty" parts.
You didn't specify color. Color will effect price as SS costs more than porcelain black or white.
By slide-in, your control panel will be on the front of the unit, not a rear, upper control panel as that is a free-standing range (they name the types, i didn't).
From what you're describing as your "needs," you're looking at a basic entry level unit these days with few bells and whistles. If you level up to convection personally i love convection), that would be your next price point.
Shop slide-in gas ranges that are designed to easily fit between your kitchen cabinets, combining a gas cooktop and an oven for more convenient cooking.

since 1996 in my homes I have owned and used KA appliances (slide in gas range which i absolutely loved). the current home (since 2002) came with GE Profile cooktop and GE Profile built in oven (convection and a separate mircrowave) which all died in (both the cooktop and microwave and oven) 16-17 years.
I'd say the GE Profile was average quality and average durability. Now I am hard on my cooking appliances and used to use them a lot. I cooked for my family of five on them extensively so they probably delivered the life they should have. Would I buy GE Profile again? No. for my needs and features, I am buying GE Cafe for my new home. This was a tough choice as the builder offers this as their upgraded Professional line of appliances.
From my research, I am willing to give the Cafe brand a go as my cooking is now and will be much less intensive then when I cooked for 5+ people over the past 22 years. But my first plan was a dual fuel KA 36" slide in commercial style.
I am a personal fan of KA/Whirlpool products (not fridges, but cooktops and range/slide-ins). I replaced my current home's GE stuff with all KA when i needed new appliances. I bought the KA top fo the line drop in cooktop, 36". it has all the features I wanted and needed. From automatic burner ignition/reignition, illuminated "on" knobs (so i can visually see which burner i left on) to various burner outputs (5k btu lowest to 20k btu highest), i can wok and sear or delicately melt chocolate. the in-wall oven is electric convection and has a major feature set along with a built in micro/convection oven. the micro/convection oven does air frying, crisping and all other standard features. this appliance works well for us and even more now that it's mostly my wife and me for dinner.
If you stay at your feature set, you're looking at $800-1K for a good basic slide in range.
I would look at the Frigidaire, GE and KA offerings. Parts are widely available if service is ever needed. The unit you're seeking isn't overly complex so less features to break over time.
And there are some really good sales going on right now. All three of these brands are assembled in the USA (ovens/ranges). Most microwaves are made in China these days.
