LightRoom is a good solution for you.
How many is a "bunch"?
What are you going to do with the jpegs?
You do realize that a RAW file should be processed - hence the name RAW.
I basically do this all the time. I process a RAW file in LR Classic, then "export" it as a jpeg. I select the size of a jpeg file that I want based on what I will use the jpeg for.
In LR, you can go a long ways with just the Library Module. Select the files you want to process. Under Quick Develop, select the appropriate White Balance, then hit "Auto". With the latest LR, this will get you quite close.
If you want more, go to the develop module, be sure Auto Sync is on, then give the 1st photo some sharpening and some noise reduction.
Then, go to "Export" and export them all as jpegs.
Now for me, I tend to do this one file at a time. I first rate them, select the ones i want to process, then I process them all individually in the Develop module.. Depending on what I will do with them, I export them after I am finished developing.
