I HAVE kept all my filters from my film camera day... (show quote)
I should have added that I shoot Jpegs and detest post processing.

These cameras may have any of a number of response curves, but if they are orthochromatic, they are equally responsive to all colors of light.
Don't you mean "panchromatic"? Ortho is unequally sensitive to blue. That is why old photos tend to have a white sky. Early films and plates were orthochromatic.

Then continue shooting JPEG and try doing so with the red filter. If the result is too dark, bump up the EV setting.

Yep. Using JPEGs only is a case where traditional filters can be of some use.
Beware of using Auto White Balance, though! You don't want to negate the effect of the filter, so do a custom/manual/preset white balance in the light falling on the scene BEFORE you attach the filter. That will ensure you get the full effect of the filter, rather than canceling it out electronically.

Have you tried the B&W and filter options of your current camera? Have you adjusted the contrast setting of the camera, in general and / or with the B&W and filter settings?

I am thinking of buying orange and red filters for use on a digital camera to increase contrast with B&W images. Will this work?
I delved into the menu for my camera and learned that it DOES have built in yellow, orange and red filters for use with monochrome. Thanks to whoever it who suggested that!

I suspect that these filters are implemented in camera firmware and do this the same way that external software would do this. Should provide an easy and fun way to work with B&W. Post some examples using these filters.

Adding that I looked at my Olypus EM5ii and it too had the option of adding colored filters to B&W images, and I could really see the diiference with the in-camera results on the. EVF.
But I left the camera in RAW and found that the filter effects were not seen in the RAW file at all. They would have been added to a JPEG file, but I had that turned off.
***************** update ********************
Turned on JPEG files and both images are unprocessed, straight out of the camera files:
First image is with the camera red filter.
Second image is with the camera yellow filter.
Note: This camera is full spectrum IR, so your results will not be the same. But I wanted to show that using the filters does have effect.
