Like, I'm pretty sure it's most common to have subject agreement and tense (or tense/aspect?) marking fuse; and I'm pretty sure that having all of agreement, TAM, and valency markers get fused is pretty unusual; but it would be nice to know more.
Standard Arabic verbs merge all four of tense (present/past), voice (active/passive), derivational valency (over 10 possibilities) and, partially, subject agreement (3 persons, 2 genders, 3 numbers), in one beautiful soup of transfixes (ablaut). Present-tense stems may also distinguish three or four moods (indicative/subjunctive/jussive; also the energetic if subject agreement allows it), which are merged into the part of subject agreement that doesn't depend on tense/voice/valency.
In other words, Arabic finite verbs can be analyzed as consisting of three parts:
Prefix: present-tense subject agreement that varies in form depending on voice and derivational valency
Stem: the root shaped into a stem while merging tense, voice and derivational valency (see example lists below)
Suffix: past subject agreement; otherwise present-tense subject agreement that varies in form depending on mood
Here is an example of an inflecting stem adapted from the Hans-Wehr Arabic-English dictionary, listing result forms in the order present-active, past-active, present-passive, past-passive (past-tense stems don't begin with a hyphen because they only take suffixes, unlike present-tense stems which take circumfixes):
valency I 'to write [sth]' (basic transitive): -ktub- katab- -ktab- kutib-
valency II 'to make [sb] write' (productive causative): -kattib- kattab- -kattab- kuttib-
valency III 'to write to [sb] often, keep in touch' (dative applicative): -kaatib- kaatab- -kaatab- kuutib-
valency IV 'to dictate' (idiomatic high-register causative): -ktib- ʔaktab- -ktab- ʔuktib-
valency VI 'to write to each other often' (reciprocal of valency III): -takaatab- takaatab-
valency VII 'to be subscribed, registered' (pseudo-passive): -nkatib- inkatab-
valency VIII 'to copy [sth]; subscribe, register' (abstract reflexive): -ktatib- iktatab- -ktatab- uktutib- (the first -t- is an infix)
valency X 'to ask [sb] to write' (suggestive causative): -staktib- istaktab- -staktab- ustuktib-
Inuktitut and especially Yup'ik have subject+object agreement that is amusingly heavily fused with other things, such as polar interrogativity (whether the verb poses a yes-no question or not), but I don't have time to look that up at the moment.
