Kodak and Ilford.
I would go with a mid speed (ISO 100/125) film like Kodak T-Max 100, Ilford Delta 100 or Ilford FP4.
Now the why?
Back in the old days, I used to shoot Tri-X ASA-400.
The problem was, full daylight exposure was f/16 at 1/500 sec. That maxed out the camera, and I had no other usable exposure setting. So I now had an expensive box camera.
Shooting Plus-X, ASA 125 gave me about two stops more exposure control. I could shoot at f/16 at 1/125 sec.
Shooting Panatomic-X, ASA 32 gave me another two stops. I could shoot at f/16 at 1/30 sec.
By shooting a mid speed film, around ASA/ISO 100 I had some exposure control.
It was a compromise, I could not shoot in as low light as I could with Tri-X, but it did not need as much light as Panatomic-X.
On the other hand, there were several of my friends who preferred to shoot Tri-X.
So each person may have their own preference.
If you are used to using Tri-X, it might be worth sticking with it.
Whatever you choose, just use it for several months to a year.
If you hop around between different films, you won't get used to that film, and how it records the scene.
