Spacing and fontsize from caption of longtable

Question

I have a problem with the longtables, they are not in the same format as the tables. I don't fully understand the way it works.

The code is as follows:

\documentclass[
    12pt,               % tamanho da fonte
    a4paper,            % tamanho do papel. 
    english,            % idioma adicional para hifenização
    brazil              % o último idioma é o principal do documento
    ]{abntex2}
\usepackage{float}
\usepackage{listings}
\usepackage{longtable}

\begin{document}
\selectlanguage{brazil}
\frenchspacing 
\OnehalfSpacing
%%% Longtable
\begin{center}
    \ABNTEXfontereduzida
    \begin{longtable}{ p{.05\textwidth} p{.15\textwidth} p{.70\textwidth} } 
    \caption{I want this to go up and have a space from the table and to change this font size}\\
    \toprule
    \textbf{Bit}       &
    \textbf{Nome}         &
    \textbf{Descrição} \\
    \endfirsthead
    \toprule
    \textbf{Bit}       &
    \textbf{Nome}         &
    \textbf{Descrição} 
    \\
    \endhead
    \hline
    \multicolumn{3}{l}{Continua...}\\
    \endfoot
    \multicolumn{3}{c}{I want this to go down and have a space from the table}\\
    \endlastfoot
    \\
    15     & 
    NACKMOD           &
    The text seems to be different as well. I think the font size is bigger
    \\
     14     &

    \\
    \\ 
    \bottomrule
    \end{longtable}
\end{center}

This is format I wanted the longtable to be.
%%%table
\begin{table}[H]
    \ABNTEXfontereduzida
    \caption{This is the font style and size I wanted}
    \begin{center}
    \begin{tabular}{@{}p{1cm}p{2cm}p{12cm}@{}}
        \toprule
        \textbf{Bit}       &
        \textbf{Nome}         &
        \textbf{Descrição} 
        \\
        15     & 
        NACKMOD           &
        The text seems to be different as well. I think the font size is smaller.
        \\
         14     &

        \bottomrule
    \end{tabular}
    \end{center}
    \fonte{This is the distance I wanted}
\end{table}
\end{document}

The results are:

I didn't find any example that had this spacing after the table and I don't know what to look for in \ABNTEXfontereduzida (which is the format I am looking for).

Using the class abntex2 abntex2.cls (based on memoir)

(\ABNTEXfontereduzida is defined as \footnotesize)

The \rule{0pt}{6ex} in the \endfoot allows to increase the vertical space.
