I hope that this is in the vein of what you were looking for.

In a review (*Marcel Riesz’s Work on Clifford Algebras*, 1993)
of Marcel Riesz's lecture notes (*Clifford Numbers and Spinors*, 1958)
on Clifford algebras, Pertti Lounesto demonstrates a natural linear isomorphism
between $\Ext(V)$ and $Cl(V)$.

Given a symmetric bilinear form $\form{\cdot,\cdot}$ on a vector space $V$
over a field $K$ with characteristic $\not=2$,
this extends to a bilinear form on $\Ext V$.
On $k$-blades (i.e. simple $k$-vectors), we define
$$
\form{x_1\wedge\cdots\wedge x_k, y_1\wedge\cdots\wedge y_k}
= \det\form{x_i, y_j},
$$
which is to say that we take the determinant over the matrix with entries
$a_{ij} = \form{x_i, y_j}$.
For blades $A, B \in \Ext V$ with different grades we define $\form{A, B} = 0$,
and then extend by linearity to the entirety of $\Ext V$.
Though maybe not obvious when described like this,
this extension of the form on $V$ is natural,
see here and here.

With this form on $\Ext V$,
the adjoints of the exterior product
$$
\form{X \wedge Y, Z} = \form{Y, X \lcontr Z},\quad
\form{X \wedge Y, Z} = \form{X, Z \rcontr Y}
$$
(where $X, Y, Z \in \Ext V$ are arbitrary multivectors)
are found to be the *left* ($\lcontr$) and *right* ($\rcontr$) contractions
of the Clifford algebra defined by $\form{\cdot,\cdot}$ on $V$.
They are indispensable when studying Clifford algebras for applications.
There are various different conventions that can be used when defining them;
see the appendix of this preprint
(*Compendium on Multivector Contractions*, 2022)
by André Mandolesi.
It's worth noting that the alternative contractions
$$
X\lcontrr Y = \rev X\lcontr Y,\quad X\rcontrr Y = X\rcontr\rev Y,
$$
where $\rev X$ is the reverse of $X$, are particularly popular;
see Lounesto or this article
(*The Inner Products of Geometric Algebra*, 2002)
by Leo Dorst for an exposition on their basic properties.

We may note that $a \lcontr b = a \rcontr b = \form{a, b}$ for $a, b \in V$.
Now define the products
$$
aX = a\lcontr X + a\wedge X,\quad
Xa = X\rcontr a + X\wedge a,
$$
which can be seen to be exactly the Clifford algebra products of $a$ and $X$.
By this definition, this product is self-adjoint:
$\form{aX, Y} = \form{X, aY}$ with an analogous formula for $a$ on the right.
But any blade $A$ can be written as $A = a_1a_2\cdots a_k$ for some $k$
and $a_1,\dotsc, a_k \in V$ using Clifford products (which are associative);
hence
$$
\form{AX, Y}
= \form{a_1a_2\cdots a_kX, Y}
= \form{a_2a_3\cdots a_kX, a_1Y}
= \form{a_3a_4\cdots a_kX, a_2a_1Y}
= \form{X, \rev AY}.
$$
By linearity, the same holds for when $A$ is an arbitrary multivector.
Thus,
$$
\form{X, Y} = \form{X\cdot 1, Y} = \form{1, \rev XY} = \form{\rev XY}_0.
$$

It's worth noting that the contractions
have a very direct connection with the Clifford product.
For any $X, Y \in \Ext V$,
$$
X\lcontr Y = \sum_{j=0}^n\sum_{k=0}^n\form{\form{\rev X}_j\form{Y}_k}_{k-j},\quad
X\rcontr Y = \sum_{j=0}^n\sum_{k=0}^n\form{\form{X}_j\form{\rev Y}_k}_{j-k},
$$
where $\form{\cdot}_l = 0$ if $l < 0$.
For $a \in V$ and $X \in \Ext V$ in particular,
$$
a\lcontr X = \frac12(aX - \hat Xa),\quad
X\rcontr a = \frac12(Xa - a\hat X),
$$
where $\hat X$ is the grade involution (i.e. main involution) applied to $X$.
