Yes, you would need a GTK+3 theme that has steppers enabled.

Indeed. When I want a new GTK+ theme, I browse the themes with 
screenshots at https://www.xfce-look.org/browse/cat/135/ord/top/ (read 
more below before doing that). Unfortunately, many screenshots don't 
show how the scrollbars look like, though.

xfce4-terminal 0.6.3 in Ubuntu 16.04 was GTK+2 indeed, but it has been 
ported to GTK+3 since Ubuntu 16.10. Newer versions of Fedora will most 
likely be the same.

I have managed to show the scrollbars steppers on Greybird by editing 
the theme, but scrolling by clicking on the steppers is ridiculously 
slow (also the steppers are almost transparent):

$ mkdir ~/.themes/
$ cp -r /usr/share/themes/Greybird/ ~/.themes/
$ mousepad ~/.themes/Greybird/gtk-3.0/gtk-contained.css
replace
     -GtkScrollbar-has-backward-stepper: false;
     -GtkScrollbar-has-forward-stepper: false; }
with
     -GtkScrollbar-has-backward-stepper: true;
     -GtkScrollbar-has-forward-stepper: true; }
restart xfce4-terminal

So I went to xfce-look.org, and searched for a GTK+3 theme with the 
steppers pre-enabled, and found this one 
https://www.gnome-look.org/p/1013663/ (which is ugly but would serve the 
test). Scrolling the terminal with it is also painfully slow.

The method I use to scroll the terminal myself is by creating a vertical 
border to scroll with the touchpad, and also Shift+PageUp and 
Shift+PageDown will scroll one page of terminal output.

If editing the Greybird theme was not enough for you, you may want to 
remove this modified version:
$ rm -rf ~/.themes/Greybird/
